After revisiting the genesis GPIO table and schematics for EVT closure,
I discovered several missing and/or incorrectly documented GPIO pin
mappings.
Now the GPIO pin names and functions should match what's written in the
latest schematics.

The timeout is never reached when the codec is functioning properly.
Using a small timeout value can result in spurious errors with some
codecs, e.g. a codec that is slow to respond but operates correctly.
When a codec is non-operative, the timeout is only reached once per
verb table, thus the impact on booting time is relatively small. So,
use a reasonably long enough timeout to cover all possible cases.
Remove the unconditional 25 µs delay and increase the timeout delay.
The new value of 1 ms is the maximum of all existing implementations.
Currently, the only boards using this code are AMD reference boards:
- AMD Bilby
- AMD Mandolin
- AMD Padmelon

Use the MRC cache API for asurada, and sync dramc_param.h with dram
blob (CL:*3674585). With this change, the checksum, originally stored in
flash, is replaced with a hash in TPM. In addition, in recovery boot,
full calibration will always ne performed, and the cached calibration
data will be cleared from flash.
This change increases ROMSTAGE size from 236K to 264K. Most of the
increase is caused by TPM-related functions.
Add new API mtk_dram_init() to emi.h, so that 'dramc_parameter' can be
moved to soc folder.
With this CL, there is no significant change in boot time. Normal AP
reboot time (fast calibration) is consistently 0.98s as before, so
this change should not affect the result of platform_BootPerf.

This patch is trying to address some of the concerns raised in CB:50247
after the patch had landed. The preference for alphabetized headers was
just supposed to discourage leaving headers completely unordered, and
wasn't intended to disallow other intentional include orderings such as
grouping local includes after system ones or specific ordering
constraints that exist for technical reasons. This patch adds a few more
sentences to try to clarify that.
