mb/google/skyrim: Pass Ti50 IRQ to PSP

It shouldn't be assumed that all variants of skyrim will use the same
gpio for TPM interrupts.

Use the PSP's new mailbox command to tell it what gpio the tpm interrupt
comes in on.

BUG=b:248193764
TEST=tast run <ip> hwsec.TPMContest
     Verify log entry:[DEBUG]  PSP: Setting TPM GPIO to 18...OK
     Use incorrect GPIO in mailbox cmd and verify TPMContest test failed.
