Coverity believes there is a path where StdHeader is possibly
null. This *should* be incorrect, since the header is actually
initialized through the module dispatch framework, though Coverity
can't see it due to the extensive type-punning. However, the control
flow is so dizzingly complicated that I'm not even completely sure,
so adding an extra assert to be careful won't hurt anyway.

The next changes are made support C_ENVIRONMENT_BOOTBLOCK:
- Add car_stage_entry() function bootblock-c_entry() functions.
- Specify config DCACHE_BSP_STACK_SIZE and C_ENV_BOOTBLOCK_SIZE.
- Add bootblock_c_entry().
- Move init from car_soc_XXX_console_init() to bootblock_soc_XXX_Init()

This patch adds support to read SPI flash in Dual SPI mode, where both
MISO and MOSI lines are used for output mode (specifically Fast Read
Dual Output (0x3b) where the command is still sent normally, not Fast
Read Dual I/O (0xbb) whose additional benefit should be extremely
marginal for our use cases but which would be more complicated to
implement). This feature needs to be supported by both the flash chip
and the controller, so we add a new dual_spi flag (and a new flags field
to hold it) to the spi_flash structure and a new optional xfer_dual()
function pointer to the spi_ctrlr structure. When both are provided,
Dual SPI mode is used automatically, otherwise things work as before.
This patch only adds the dual_spi flag exemplary to all Winbond and
Gigadevice chips, other vendors need to be added as needed.

All SPI flash chip drivers currently in coreboot use the generic read
functions (spi_flash_cmd_read_fast()/_slow()) as their read callback.
The only use case for specialized read callbacks we have left is with
specialized flash controllers like Intel fast_spi (which sort of
impersonate the flash chip driver by implementing their own probe
function).
This patch unifies the behavior for all normal flash drivers by making
the read callback optional and letting them all fall back to a default
read implementation that handles normal fast/slow reading. Most of the
drivers used to install the respective callback after checking
CONFIG_SPI_FLASH_NO_FAST_READ, but some hardcoded either slow or fast
writes. I have found no indications for why this is and spot-checked
datasheets for affected vendors to make sure they all support both
commands, so I assume this is just some old inaccuracy rather than
important differences that need preserving. (Please yell if you
disagree.)
Also take the opportunity to refactor some of the common spi_flash.c
code a bit because I felt there are too many nested functions that don't
really do enough on their own, and centralizing stuff a bit should make
it easier to follow the code flow. (Some of this is in preparation for
the next patch.)

This patch changes the Gigadevice SPI flash driver to adopt the same

individual chips that was implemented for Winbond last year. This cuts
the size of the hardcoded info nearly in half and should save us a few
hundred bytes in every stage.

The SPI transfer speed logging in cbfs_spi is super useful, doesn't get
in the way (just adding one line per stage, essentially) and should have
no notable overhead. Let's enable it by default for the BIOS_DEBUG log
level rather than having to recompile to get it.
Also fix an issue with building this code on MIPS due to lack of 64-bit
division primitives. (This means MIPS and arm32 board may display
incorrect results when reading more than 4MB in a single transfer, which
sounds very unlikely.)

The code in cpu/intel/car/romstage.c Does most of the things like
setting up timestamps, stack guards, entering postcar.
A functional difference is that the FSP header is searched for twice
instead of passed from the CAR entry to the C code. When using
C_ENVIRONMENT_BOOTBLOCK this needs to be done anyway (or a special
linker symbol kept across multiple stages is needed, which is likely
not worth the speedup).

This moves FSP1.1 to use postcar stage to tear down CAR.
On platforms with USE_GENERIC_FSP_CAR_INC the FSP header is found
during the postcar stage so there is no need to push to save it
in CAR global variables.
On FSP1.1 platforms with an open source CAR implementation (Skylake,
even though it still runs the FSP-T), the
soc/intel/common/blocks/cpu/car/exit_car.S code tears down CAR.
This also uses common functions to set up the MTRR to use after
CAR is torn down.

`pei_data` was a struct with blob parameters from pre-FSP times.
Somehow, it sneaked into upstream FSP1.1 support (probably because
early board ports were written for a different blob). When added
upstream, its usage was already perverted. It was declared at SoC
level but mostly used to pass mainboard data from mainboard code
to itself and FSP data from FSP code to itself. Now that no board/
SoC code uses it anymore, we can finally drop it.
