This does not use loops to compute timings but uses DIV_ROUND_UP.
Another thing affected by this patch are minimum timings. Presumably
those only need to be guarded against on DDR3. With this change
timings are set up like vendor (with tWTR below previous minimum)

The ALSB gnvs variable is used to load the OpRegion memory
address into the ASLS register on the S3 resume path, and must
therefore first be set on the normal boot path.
This patch brings Haswell in line with SNB/IVB/Nehalem, which
already save the OpRegion address in ASLB.

On boards that are able to take two DIMMs per channel the
command rate should be 2T. It is possible to use 1T with
load reduced "1T" DIMMs, but it's not clear how to detect
those DIMMs. Raminit might fail for those who do not have
such DIMMS installed.
Hardcode command rate of 2T to make sure raminit works on
dual DIMM per channel boards (currently only desktop boards).
The command rate of 1T is still tested if only 1 DIMM per
channel is present.
Will decrease performance on quad slot mainboards, if two DIMMs
are installed in one channel and previously 1T have been selected.
Tested on ASRock B75 Pro3-M.

Provide all gfx init methods as a Kconfig `choice`. This elimates the
option to select native gfx init along with running a Video BIOS. It's
been only theoretically useful in one corner case: Hybrid graphics
where only one controller is supported by native gfx init. Though I
suppose in that case it's fair to assume that one would use SeaBIOS to
run the VBIOS.
For the case that we want the payload to initialize graphics or no
pre-boot graphics at all, the new symbol NO_GFX_INIT was added to the
choice. If multiple options are available, the default is chosen as
follows:
* NO_GFX_INIT, if we add a Video BIOS and the payload is SeaBIOS,
* VGA_ROM_RUN, if we add a Video BIOS and the payload is not SeaBIOS,
* NATIVE_VGA_INIT, if we don't add a Video BIOS.
As a side effect, libgfxinit is now an independent choice.

maintain and free the space for spi_flash structure as required.
