OMAP_MCBSP_READ()/_WRITE() macros and omap_mcbsp_read()/_write() functions
accept McBSP register base address as an argument. In order to support
caching, that must be replaced with an address of the omap_mcbsp structure
that would provide addresses for both register AND cache access.
Since OMAP_ prefix seems obvious in macro names, drop it off in order to
minimize line wrapping throughout the file.

There are several places where readw()/writew() functions are used instead of
OMAP_MCBSP_READ()/WRITE() macros for manipulating McBSP registers. Replace
them with macros to ensure consistent behaviour after caching is introduced.

As the NFC controller has different addresses on imx21 and imx27 there
are two different devices needed if not relying on the overloaded cpp
macro NFC_BASE_ADDR. So some cpp magic is added to minimize code
duplication.
As obviously these two defines need different names, the name of the old
device is #defined to the new one when building for only one of imx21 or
imx27.

ARMv6 and ARMv7 CPUs can perform speculative prefetching, which makes
DMA cache coherency handling slightly more interesting. Rather than
being able to rely upon the CPU not accessing the DMA buffer until DMA
has completed, we now must expect that the cache could be loaded with
possibly stale data from the DMA buffer.
Where DMA involves data being transferred to the device, we clean the
cache before handing it over for DMA, otherwise we invalidate the buffer
to get rid of potential writebacks. On DMA Completion, if data was
transferred from the device, we invalidate the buffer to get rid of
any stale speculative prefetches.

This follows the parisc change to ensure that tracehook_signal_handler()
is aware of when we are single-stepping in order to ptrace_notify()
appropriately. While this was implemented for 32-bit SH, sh64 neglected
to make use of TIF_SINGLESTEP when it was folded in with the 32-bit code,
resulting in ptrace_notify() never being called.
As sh64 uses all of the other abstractions already, this simply plugs in
the thread flag in the appropriate enable/disable paths and fixes up the
tracehook notification accordingly. With this in place, sh64 is brought
in line with what 32-bit is already doing.
