Do not disable branch prediction, as this has a big performance impact.
After re-enabling branch prediction, __loop_delay() runs 16 (Cortex A15)
or 11 (Cortex A9) times faster than before.

As usual, a bunch of commits, mostly adding drivers and other options to
defconfigs because it makes sense to have them enabled on various development
or product boards. Too much to enumerate each here.
There's an introduction of a pxa_defconfig, since PXA finally will allow
building a shared kernel for all boards. With this, we can hopefully
remove a bunch of individual defconfigs down the road but it requires
a bit of real life testing and transition period.

The purpose of this patch is to start the process of replacing both
ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI with ARCH_RENESAS.
RENESAS seems to be a more appropriate name than SHMOBILE for the majority
of Renesas 32-bit ARM based SoCs. The name is conveniently also (newer)
ARM64 based SoCs.
This patches only addresses 32-bit ARM based SoCs. Proposed support for
the ARM64 based r8a7795 SoC already uses ARCH_RENESAS which selects
ARCH_SHMOBILE.
