mb/google/rex: Configure ISH UART TX/RX as NC
This patch reverses ISH UART pin configuration to allow ISH to enter into suspend mode. This UART port is for debugging purposes. BUG=b:302612549 TEST=On Google/rex platform with ISH enabled, do suspend_stress_test This test must pass Signed-off-by: Bernardo Perez Priego <bernardo.perez.priego@intel.com> Change-Id: I8aba45420744a3990e1f9637c3b31ea2e0f78f87 Reviewed-on: https://review.coreboot.org/c/coreboot/+/78049 Reviewed-by: Tanu Malhotra <tanu.malhotra@intel.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Kapil Porwal <kapilporwal@google.com> Reviewed-by: Subrata Banik <subratabanik@google.com>
