A few notable changes:
- Microcode init is done in assembly during the CAR init.
- The DCACHE_BSP_STACK_SIZE is set to 0x2000, which is the same size
against which the romstage stack guards protected.
- The romstage mainboard_lpc_init() hook is removed in favor of the
existing bootblock_mainboard_early_init().

It is only called in ramstage. Even if it was called in
romstage, execution flow is such that BSP and AP CPUs
should not be able to enter update_microcode() routine
concurrently.
Also the Kconfig guarding the spin_lock() calls are not
selected nor are the lock variables declared for these
platforms.

Fix regression from commit ecea916
cpu/intel/common: Extend FSB detection to cover TSC
MSR_EBC_FREQUENCY_ID (0x2c) was not defined for affected
CPU models and rdmsr() caused reset loops. Implementations
deviate from public documentation.
Change to IA32_PERF_STATUS (0x198) already used in i945/udelay.c
to detect FSB to TSC multiplier.

Initialize the input_hertz and uart_pci_addr fields of the lb_serial
struct to prevent later undefined reads in lb_add_serial(). This was
done for exynos5420 in commit ff94e00362 (soc/samsung/exynos5420/uart.c:
Init new serial struct variables), and this patch finishes the rest.
Note that not all of the drivers can have the UART PCI address
configured at build time, so a follow-up patch will be needed to correct
those ones.

These platforms return to romstage from FSP only after
already having torn CAR down. A copy of the entire CAR
region is available and discoverable via HOB.
Previously, CBMEM console detected on-the-fly that CAR
migration had happened and relocated cbmem_console_p
accoringlin with car_sync_var(). However, if the CAR_GLOBAL
pointing to another object inside CAR is a relative offset
instead, we have a more generic solution that can be used
with timestamps code as well.

With C_ENVIRONMENT_BOOTBLOCK, CONFIG_DCACHE_BSP_STACK_SIZE needs to be
set to define a stack region that can be shared over all stages using
CAR. It makes sense to use that Kconfig option's value instead of a
hardcoded value. This will result in less false positives when the
stack size is big, for instance with FSP using the coreboot stack.
In many configurations with C_ENVIRONMENT_BOOTBLOCK the stack_base is
at the base of CAR. If the stack grows too large it operates out of
CAR, typically resulting in a hang. Therefore the stack guards are
extended to cover 256 bytes at the base to at least provide a warning
when the romstage is dangerously close of running out of stack.
