soc/tegra: cbb: Set ERD on resume for err interrupt
Set the Error Response Disable (ERD) bit to mask SError responses
and use interrupt-based error reporting. When the ERD bit is set,
inband error responses to the initiator via SError are suppressed,
and fabric errors are reported via an interrupt instead.
The register is set during boot but the info is lost during system
suspend and needs to be set again on resume.
