Attention is currently required from: Tarun Tuli, Subrata Banik.

Hello build bot (Jenkins), Tarun Tuli, Kapil Porwal, Ivy Jian,

I'd like you to reexamine a change. Please visit

https://review.coreboot.org/c/coreboot/+/69612

to look at the new patch set (#2).

Change subject: mb/google/rex: Add `disable_gpio_export_in_crs` for rex

mb/google/rex: Add `disable_gpio_export_in_crs` for rex

None of the touchscreens (over I2C) used in the rex program requires
exporting GPIOs in the ACPI _CRS method.

This can cause i2c devices to malfunction or cause timing
sequence violations if ACPI exports a PowerResource for the
device that uses GPIOs that are also exported in _CRS.

BUG=none
TEST=Able to build and boot Google, Rex platform.

Without this patch:

[ERROR]  I2C: 00:10: Exposing GPIOs in Power Resource and _CRS

With this patch:

None
