ARM: shmobile: Consolidate SCU mapping code
Currently the SCU registers are mapped in SoC-specific code, using
different methods, all involving the static mapping set up from
machine_desc.map_io():
- On emev2, a static (non-identity) mapping is used, with ioremap().
As the static mapping uses the MT_DEVICE type, ioremap() reuses it,
and the returned virtual address is suitable for passing to
shmobile_smp_hook(),
- On sh73a0 and r8a7779, a static identity mapping is used, with the
legacy IOMEM() macro.
As the static mapping uses the MT_DEVICE_NONSHARED type, replacing
IOMEM() by ioremap() would create a new mapping, whose virtual
address cannot be passed to shmobile_smp_hook().
Move the mapping of the SCU registers from SoC-specific code to common
code, always using ioremap(). To work in the absence of a static
mapping, this requires passing the physical SCU base address to
shmobile_smp_hook().
