usb: gadget: r8a66597-udc pio to mmio accessor conversion.

r8a66597-udc is erroneously using PIO routines on MMIO registers, which
presently blows up for any platform that elects to either override or do
away with PIO routines. This managed to work for the common cases since
the PIO routines were simply wrapped to their MMIO counterparts. This
switches over to using the MMIO routines directly, and enables us to kill
off a lot of superfluous casting in the process.

usb: r8a66597-udc unaligned fifo fix

Rework the r8a66597-udc fifo code to avoid unaligned accesses.

Without this patch unaligned exceptions will degrade the
USB performance. The exceptions come from the fact that
the usb fifo data buffers may be misaligned.

This patch updates the fifo access code to only use
insl()/outsl() and insw()/outsw() in the case of properly
aligned data buffers. The fallback case is that inl()/inw()
are used for misaligned buffer reads together with outb()
that is used for misaligned buffer writes.

usb: r8a66597-udc buffer management update

This patch updates the r8a66597-udc buffer management code.

Use fixed buffers for bulk and isochronous pipes, also make
sure to handle the isochronous-as-bulk case. With fixed buffers
there is no need to keep track of used buffers with bi_bufnum.

Also, this fixes a potential buffer offset problem where the
base offset incorrectly varies with the number of pipes used.

The m66592 driver recently got fixed in a similar way.
