Subject: ARM: shmobile: Add second I/O range for r8a7790 PFC

Add the GPIO I/O memory range to the r8a7790 PFC device.

This extra I/O memory range is needed when using the PFC
tables to drive both pin functions (using PINCTRL or
function GPIO for old code) and actual GPIO. The goal is
however to use a separate GPIO driver in the long run
and when that happens this extra I/O memory range can
be removed.

Subject: ARM: shmobile: force enable of r8a7790 arch timer

Implement a SoC-specific timer init function for
r8a7790 that makes sure the architected timer
is started regardless of boot loader setting.
