When the components like LCM ID are not installed (i.e., NC), ADC will
return some value with much larger variation from standard value (out of
the tolerance we set). To support that, we should check tolerance only
on non-NC voltages.
Also improve the error messages so we can see the ADC raw values
instead of simple assertion error (which makes debugging more difficult
since we have to build another firmware image just to print the values).

Kukui is using MIPI display panel and needs some identifier to tell
payloads which LCD module is installed, and to select right kernel
device tree. Following Scarlet, the decision is to embed LCD module ID
as part of SKU ID.
The LCM ID is using a different voltage mapping table from the rest.
Considering the complexity in computation of SKU ID, it is better to
move the cache logic from get_index to caller.
Also revise the mapping table since ADC on 8183 only supports 12
levels.

Kukui with vboot enabled will build with `detachable_ui`, which needs
larger space in CBFS for more complicated assets. So we need to revise
FMAP sections:
- BOOTBLOCK (not really used) only needs <= 32K.
- GBB can be much smaller since assets moved from GBB to CBFS.
- FMAP is re-ordered (with the cost of less efficient in bsearch) so CBFS can
get larger continuous space.
- COREBOOT(CBFS) should take all space left.
Since FMAP and COREBOOT have changed location, the system will need to
reflash EC (which contains the new bootblock) as well.

The romstage main() entry point on arm64 boards is usually in mainboard
code, but there are a handful of lines that are always needed in there
and not really mainboard specific (or chipset specific). We keep arguing
every once in a while that this isn't ideal, so rather than arguing any
longer let's just fix it. This patch moves the main() function into arch
code with callbacks that the platform can hook into. (This approach can
probably be expanded onto other architectures, so when that happens this
file should move into src/lib.)
Tested on Cheza and Kevin. I think the approach is straight-forward
enough that we can take this without testing every board. (Note that in
a few cases, this delays some platform-specific calls until after
console_init() and exception_init()... since these functions don't
really take that long, especially if there is no serial console
configured, I don't expect this to cause any issues.)

MT8183 only allows booting from eMMC, so we have to do eMMC emulation
from an external source, for example EC, which makes the size of
bootblock very important.
A fully functional bootblock (that can boot into verstage or romstage)
is about 38000 bytes. If self decompression (CONFIG_COMPRESS_BOOTBLOCK)
is enabled, only 25088 (66%) bytes are needed.
Inspired from crosreview.com/1070018.
