this patch enables DMA support for SiRFSoC SPI driver, if both
buffers and length are aligned with DMA controller's hardware
limitation, use generic SiRF generic dmaengine driver.
for PIO, SiRF SPI controller actually is using rx to trigger rx,
that means if we write any word to tx fifo, we will get a word
from rx fifo. for DMA, we use two different channel for tx and
rx, and issue them both for every transfer.

Commit 6e0650 (ASoC: wm8994: Use SOC_SINGLE_EXT() instead of open-coding
it) went too far and converted a DAPM control to use SOC_SINGLE_EXT()
which crashes. Revert that portion of the patch.

Hook in the per-CPU boot and sleep code in the shared
mach-shmobile SCU code. CPUs may be kept in the asm
routine until ->boot_secondary() when the per-CPU
boot vector is installed. At the end of ->die() the
asm sleep routine is invoked.

Add per-CPU SMP boot / sleep code that can be used by all
SoCs included in mach-shmobile.
The boot code reads out the per-CPU MPIDR id value and
matches it with the value stored for any CPU number, and
if there is a match and the boot function is set as well
then the boot function will be executed.
The sleep code simply uses WFI and then jumps back to the
boot code to see if anyone has asked to wake up that CPU,
if not it will sleep again.
