[PATCH v3 07/11] ARM: shmobile: r8a7740/armadillo legacy: Add A4MP pm domain support

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

v3:
  - No changes,
v2:
  - Also hook up HDMI-Link, which was not documented in the datasheet as
    belonging to A4MP,
  - Really add A4MP and drop the FIXME, as a fix for the interrupt storm
    is available.
