[PATCH 07/11] [WIP] ARM: shmobile: r8a7740/armadillo legacy: Add A4MP pm domain support

Add support for the A4MP power domain, and hook up the FSI hardware block.
This domain also contains the SPU2, FMSI, and BBIF2 hardware blocks,
but these are currently not used by any driver.

FIXME: A4PM is not added, as it causes "irq 163: nobody cared" (irq 163
       is registered by sh-mobile-hdmi), either on boot, or, when trying
       to fix it using pm_domain_always_on_gov, on resume.
