[PATCH/RFC] ARM: Rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY

SH-Mobile platforms are transitioning from non-multiplatform to
multiplatform kernel. A new ARCH_SHMOBILE_MULTI configuration symbol has
been created to group all multiplatform-enabled SH-Mobile SoCs. The
existing ARCH_SHMOBILE configuration symbol groups SoCs that haven't
been converted yet.
This arrangement works fine for the arch/ code, but lots of drivers
needed on both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI depend on
ARCH_SHMOBILE only. In order to avoid changing them, rename
ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY, and create a new boolean
ARCH_SHMOBILE configuration symbol that is selected by both
ARCH_SHMOBILE_LEGACY and ARCH_SHMOBILE_MULTI.

This patch is an alternative approach to adding ARCH_SHMOBILE_MULTI or ARM
dependencies to all the SH-Mobile-related drivers (see
http://www.spinics.net/lists/arm-kernel/msg283128.html). If accepted I will
modify the previous series to only add COMPILE_TEST support without touching
the other dependencies.
I believe this approach to be simpler. It will also not required dropping the
ARCH_SHMOBILE_MULTI dependency from all drivers when we will eventually get
rid of the non-multiplatform platforms and rename ARCH_SHMOBILE_MULTI to
ARCH_SHMOBILE.
