powerpc/64: Sanitise common exit code for interrupts
Interrupt code is shared between Book3E/S 64-bit systems for interrupt
handlers. Ensure that exit code correctly restores non-volatile gprs on
each system when CONFIG_INTERRUPT_SANITIZE_REGISTERS is enabled.
Also introduce macros for clearing/restoring registers on interrupt
entry for when this configuration option is either disabled or enabled.
