Use the same naming convention for DMA traffic MMRs (most were legacy
anyways) so we can avoid useless ifdef trees.

Same goes for MDMA names -- this actually allows us to undo a bunch of
ifdef redirects that existed for this purpose alone.

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.

If the kernel's init section is merged back into the main memory region
during boot (which it should since that is how we've laid out the kernel
linker map), we want to make sure that these aren't counted as independent
regions.  Otherwise, if a large mapping is attempted which starts in the
init region and extends into the main memory region, the access_ok func
will deny it.  This leads to weird messages during runtime like "unable
to map xxx library" from the ldso but upon running the application again,
everything works fine.

So if the address of the end of the init region is the same as the start
of the main memory region, simply enlarge the memory region to include
the init region.

Many Blackfin parts group sets of pins into a single functional unit.
This means you cannot use different pins within a group for different
peripherals.  Our resource conflict checking thus far has been limited
to individual pins, so if someone tried to grab a different pin from
the same group, it would be allowed while silently changing the other
pins in the same group.

One common example is the pin set PG12 - PG15 on BF51x parts.  They
may either be used with SPI0 (1st function), or they may be used with
PTP/PWM/AMS3 (3rd function).  Ideally, we'd like to use PG12 - PG14
for SPI0 while using PG15 with AMS3, but the hardware does not permit
this.  In the past, the software would allow the pins to be requested
this way, but ultimately things like the Blackfin SPI driver would
stop working when the hardware rerouted to a different peripheral.
