Use the %pr printk specifier to print resource variables. This fixes
warnings on platforms where resource_size_t has a different size than
int.

Add information to the shared APMU code regarding
the APMU instance used to control the CA7 cores.
This can be used on r8a7790 and r8a73a4, but should
most likely be converted to DT in the future.

Extend the APMU code with a check to only allow boot
of CPU cores that sit in the same cluster as CPU0.
This makes it possible for people to use the r8a790
CA7 boot mode with CA7-cores only. The default CA15
boot mode will enable CA15 cores only. This is an
intentional software limitation to cope with lacking
scheduler support.
By removing this patch it is possible to run all 8 cores
in parallel, but this is not recommended without out of tree
scheduler modfications or custom user space code to control
the CPU affinitiy.

Introduce shared APMU SMP code for mach-shmobile. Both SMP boot up
and CPU Hotplug is supported. This version does not use DT but
if needed this will be added as an incremental feature patch.
The code is designed around CONFIG_NR_CPUS and should in theory support
any number of APMUs, however due to the current DT-less static design
only a single APMU is supported.
