The common asm-generic non-atomic bitops.h defines test_bit() for us, but
we need to use our own version.  So redirect the definition of this func
to avoid having to inline the rest of the asm-generic file.

Rather than maintain Kconfig entries where people have to enter raw
numbers and hardcode lists of addresses/pins in the driver itself,
push it all to platform resources.  This lets us simplify the driver,
the Kconfig, and gives board porters greater flexibility.

In the process, we need to also start supporting the early platform
interface.  Not a big deal, but it causes the patch to be bigger than
a simple resource relocation.

All the Blackfin boards already have their resources updated and in
place for this change.

The defBF512.h header exists only to include defBF51x_base.h, and it is
the only place where defBF51x_base.h is included.  So move the contents
of the defBF51x_base.h header into the defBF512.h header.

Same situation for the other def/cdef pairs.

The main asm/blackfin.h header will pull in mach/blackfin.h to get
all the fun Blackfin defines.  So having any of the sub-mach headers
trying to include asm/blackfin.h makes no sense -- punt it.

The mach/blackfin.h header takes care of including the part-specific
def headers which in turn will include any other needed def file.
Similarly, it takes care of pulling in the part-specific cdef header.
So move this logic out of the blackfin.h when necessary.

Further, make sure the cdef headers do not waste time including the
def headers again.

Since all parts need the common def/cdef headers, move this logic
out of the part-specific headers and into the mach/blackfin.h file.

Finally, we need to split the BF539 def header since the BF538 does
not have MXVR and we don't want to expose those MMRs.

So now all parts should have the same behavior:
	mach/blackfin.h
		asm/def_LPBlackfin.h
		part-specific def.h
		if ! asm
			asm/cdef_LPBlackfin.h
			part-specific cdef.h
And the sub def/cdef headers only tail into what they need.

We don't want the BF533 to be different in terms of its MMR headers, so
merge the FIO_FLAG helpers back into the normal place.  To avoid circular
dependencies with headers, turn the inline C funcs into CPP defines.  Not
like there will be any code size differences.

Soon resource data will get automatically
populated from a set of autogenerated data
from TI's hardware database for the OMAP
platform.

Such database, might not have resources at
the expected order by the current drivers.

While we could hack in some exceptions to
that tool to generate resources in a specific
order, it seems less fragile to use the
resource name instead. That way, no matter
what order the resources are generated, the
driver still work.

Modified the OMAP, Blackfin and Davinci
architecture files to add the name of the IRQs
in the resource structures and musb driver to
use the platform_get_irq_byname() api to get
the device and dma irq numbers instead of using
the index.
