struct fraction is slooooooooooow. This patch adds a simple 64-bit
(32-bits integral, 32-bits fractional) fixed-point math API that is
*much* faster (observed roughly 5x speed-up) when doing intensive
graphics operations. It is optimized for speed over accuracy so some
operations may lose a bit more precision than expected, but overall it's
still plenty of bits for most use cases.
Also includes support for basic trigonometric functions with a small
lookup table.

This change adds following two helper functions:
1. variant_uses_v3_schematics() - Check whether the variant is using
v3 version of schematics.
2. variant_has_active_low_wifi_power() - Check whether the variant is
using active low power enable for WiFi.
In addition to this, Kconfig options are reorganized to add two new
configs - VARIANT_SUPPORTS_PRE_V3_SCHEMATICS and
VARIANT_SUPPORTS_WIFI_POWER_ACTIVE_HIGH. This allows the helper
functions to return `true` early without checking for board version.
Eventually, when a variant decides to drop support for pre-v3
schematics, it can be dropped from selecting
VARIANT_SUPPORTS_PRE_V3_SCHEMATICS. Similarly, when the variant
decides to drop support for active high power enable for WiFi, it can
be dropped from selecting VARIANT_SUPPORTS_WIFI_POWER_ACTIVE_HIGH.

Perform the same operations as the RCBA reg script did, but directly
writing the corresponding registers. Some of these operations could be
simplified, but it is not done on this commit to ease verification.

The "normalized" boot mode is only used in a single place, so there's no
need to use a variable. Also, reword the associated comment, which seems
to be unnecessarily vague: the hardcoded assumptions are inside the MRC.

then runs verstage_main. It uses hardware hashing to increase the speed

of blindly defaulting to gcc/g++, except when not building an image
