drivers: firmware: psci: add INVALID_ADDRESS return value

Browse source

PSCI 1.0 introduces the INVALID_ADDRESS return value for functions
that take an address as input parameter (eg CPU_SUSPEND).

This patch adds INVALID_ADDRESS return value to kernel code and
updates the PSCI to linux error conversion to take it into account.

The kernel error value associated to INVALID_ADDRESS is set to
the error returned when the PSCI error code is INVALID_PARAMETERS
to comply with current call sites expected return value, given
that the kernel at present has no use for the additional error
information reported.
