mb/google/guybrush: Move GSC_SOC_INT_L from GPIO_3 to GPIO_85
GSC_SOC_INT_L gpio is used by Google Security Chip (GSC) to interrupt
SoC when the SoC is in S0 state. Hence use GPIO_85 which is in S0 domain
and save the GPIO_3 in S5 domain for other use-cases. This move applies
to all board except:
* Guybrush
* Nipperkin board version 1
Update the GPIO configuration, device tree configuration accordingly.
BUG=b:202992077
TEST=Build and boot to OS in Guybrush and Nipperkin. Ensure that the SoC
<-> TPM communication is working fine.
