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 Signed-off-by: Subrata Banik <subratabanik@google.com> Change-Id: I578a60eff27f94d6dc94b900604bc7560337d60b Reviewed-on: https://review.coreboot.org/c/coreboot/+/69612 Reviewed-by: Ivy Jian <ivy.jian@quanta.corp-partner.google.com> Reviewed-by: Kapil Porwal <kapilporwal@google.com> Reviewed-by: Sridhar Siricilla <sridhar.siricilla@intel.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
