spi/spi-bfin5xx: Fix flush of last bit after each spi transfer
This patch ensures that the last bit of a transfer gets correctly
flushed out of the register.

spi/spi-bfin5xx: fix reversed if condition in interrupt mode
This condition is used to determine 8 bits or 16 and 32 bits transfer.
Obviously it is reversed.

spi/bfin_spi: drop bits_per_word from client data
No other SPI controller has this field, and SPI clients should be setting
this up in their own drivers. So drop it from the Blackfin controller to
keep people from using it.

spi: irq: Remove IRQF_DISABLED
Since commit [e58aa3d2: genirq: Run irq handlers with interrupts disabled],
We run all interrupt handlers with interrupts disabled
and we even check and yell when an interrupt handler
returns with interrupts enabled (see commit [b738a50a:
genirq: Warn when handler enables interrupts]).
So now this flag is a NOOP and can be removed.

spi/bfin_spi: uninline fat queue funcs
There's no need for these queue funcs to be inlined, so drop the
markings. This shaves off a few hundred duplicated bytes.

spi/bfin_spi: use structs for accessing hardware regs
Rather than hardcoding the register sizes/offsets in this file, use the
existing struct in the spi header for reading/writing the hardware.

spi: reorganize drivers
Sort the SPI makefile and enforce the naming convention spi_*.c for
spi drivers.
This change also rolls the contents of atmel_spi.h into the .c file
since there is only one user of that particular include file.
v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be
be the predominant pattern for subsystem prefixes.
- Clean up filenames in Kconfig and header comment blocks
