mb/google/brox: Do not select HAVE_ACPI_RESUME
Brox mainboard does not reliably support S3 entry/exit. Hence do not
select HAVE_ACPI_RESUME config option. Also trigger a fail-safe board
reset if the system resumes from S3.
BUG=b:337274309
TEST=Build Brox BIOS image and boot to OS. Ensure that the _S3 name
variable is not advertised in the DSDT. Trigger a S3 entry and ensure
that on S3 exit, the board reset is triggered.
