Add SMP support for ag5evm and the sh73a0 processor.

Onlining and offlining works well, but at this point
offlined processor cores are not put into sleep mode.

There is no spinlock for syncing the secondary core
with the first one in this implementation. The code
instead relies on the cpu_online() check in __cpu_up().

Add SMP base support for R-Mobile / SH-Mobile processors.

This patch contains all base code to support CONFIG_SMP
regardless of ARCH_SHMOBILE processor type. Both local timer
and CPU hotplug are supported, but no processor specific
code is included.

At this point only the default behavior is in place, so
a single core will always be used even though CONFIG_SMP
is enabled on multicore systems.

The SMP Kconfig entry for arch/arm/Kconfig is excluded from
this patch to simplify merging.

Compiling in multiple CPUs into the same kernel binary

This patch improves the state of the AG5 clock
framework support. The main clock parent is
automatically detected, but most of the clocks
are not used by any driver or subsystem at this
point. More work is needed for support of multi
media hardware such as FSI and/or LCDC/MIPI-DSI.

This resolves a regression that I introduced in
"mmc, sh: Move constants to sh_mmcif.h". Having
examined the manual and tested the code on an AP4EVB board
it seems that the correct sequence is.

1) Write 1 to bit 31 and zeros to all other bits
2) Write zero to all bits

In sh_mmcif.c an event is used as a completion, switch over. When a
wait_for_completion*_timeout() returns, it suffices to check the remaining
time, setting an additional flag before waking up the waiting task only reduces
the race window, but does not eliminate it. This patch switches the driver to
use a completion to signal an interrupt, the only case, when an interrupt
should not wake up the waiter, is when an automatic CMD12 completes. Also fix
MODULE_ALIAS.
