The num_chipselect field for on-chip Blackfin SPI buses is supposed to
be 1 larger than the number of actual CSs available. This is because
the hardware starts counting at 1 and not 0. There is a field for "CS0",
but it is marked as "reserved" everywhere.

Now that the common header defines everything and the SPI drivers are
using it, we can drop these duplicated global namespace polluters.

Rename h/w IRQ flags handling functions to be in line with what is expected for
the irq renaming patch. This renames local_*_hw() to hard_local_*() using the
following perl command:
perl -pi -e 's/local_irq_(restore|enable|disable)_hw/hard_local_irq_\1/ or s/local_irq_save_hw([_a-z]*)[(]flags[)]/flags = hard_local_irq_save\1()/' `find arch/blackfin/ -name "*.[ch]"`
and then fixing up asm/irqflags.h manually.
Additionally, arch/hard_local_save_flags() and arch/hard_local_irq_save() both
return the flags rather than passing it through the argument list.

Split the PLL control code from the Blackfin machine-specific cdef headers so
that the irqflags functions can be renamed without incurring a header loop.

Now that the driver for the Blackfin on-chip NFC no longer uses/respects
the page_size from the platform resources (figures out the needs on the
fly), drop it from the platform resources. This fixes some build errors
since the defines no longer exists.

The standard short name for control is CTL and not CTRL. Use TWI0_xxx
even on parts that only have one TWI bus to keep things simple. Drop
all the cdef helpers since the bus driver takes care of everything.

Rather than keeping the pins in the actual driver and worrying about a
mess of Kconfig options, declare all the desired pin resources in the
boards file. This lets people easily select the specific pins/ports for
the normal emulated UART as well as GPIOs for CTS/RTS.

While we're moving the BF54x code, have the BF54xM variants select the
normal BF54x values so that the rest of the Kconfig tree doesn't need to
check the BF54xM variant everytime it wants to check the BF54x.

Bill Gatliff & David Brownell pointed out we were missing some
copyrights, and licensing terms in some of the files in
./arch/blackfin, so this fixes things, and cleans them up.
It also removes:
- verbose GPL text(refer to the top level ./COPYING file)
- file names (you are looking at the file)
- bug url (it's in the ./MAINTAINERS file)
- "or later" on GPL-2, when we did not have that right
It also allows some Blackfin-specific assembly files to be under a BSD
like license (for people to use them outside of Linux).
