mb/google/guybrush: Override SPI Fast speeds
Add support to override SPI fast speeds based on board version from both
bootblock and verstage. Overrides apply for Guybrush only and SPI speed
is overridden from 66 MHz to 100 MHz starting board version 4. This will
help to improve the boot time on board version by ~60 ms and still allow
the old boards to boot with 66 MHz.
BUG=b:199779306
TEST=Build and boot to OS in Guybrush. Perform S5->S0, G3->S0, warm
reset and suspend/resume cycles for 50 iterations each.
