fsl_udc_release() calls dma_free_coherent() with an inappropriate

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.

This patch adds a CDC EEM ethernet gadget driver. CDC EEM is a newer
USB ethernet specification that uses a simpler interface than the older
CDC ECM. This makes CDC EEM usable by a wider set of USB hardware.
By default the ethernet gadget will still use CDC ECM/Subset, but kernel
configuration and/or a module parameter will allow alternative use of
the CDC EEM protocol.
Changes since last version:
- Brought in missing RNDIS changes that caused compile error
- Modified 'sentinel CRC' checking to match EEM host driver

The included patch can be applied to the new usb gadget audio driver.
It addresses a seg-fault in uncovered in g_audio.ko.
The fault occurs in the function u_audio.c::gaudio_open_end_dev() when
device /dev/snd/pcmC0D0c (FILE_PCM_CAPTURE) is not present.
I suspect there may be similar problems with device /dev/snd/pcmC0D0p
(FILE_PCM_PLAYBACK) handling also. I leave that for the developer(s),
as I was unsure as to the side-effects of not calling
playback_default_hw_params() in the initialization phase.

This patch (as1269) fixes a bug in the way dummy_hcd handles control
URBs. Currently it returns a -EOVERFLOW error if the wLength value in
the setup packet is different from the URB's transfer_buffer_length.
Other host controller drivers don't do this. There's no reason the
two length values have to be equal, and in fact they sometimes aren't
-- a driver might set the transfer length to the maxpacket value in
order to handle buggy devices that don't respect wLength.
This patch simply removes the unnecessary check and error return.

This adds very basic otg_transceiver support, with vbus_session
and vbus_draw callbacks.
Now VBUS sensing can be handled by an external driver which registers
the otg_transceiver interface. It also allows gadget drivers to configure
the current drawn from VBUS. The UDC driver just passes their requests
along to the transceiver driver.

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.

Instead of a large (physically) linear buffer, we generate a set of
paged sk_buff, so no extra memory copy is involved. This removes
high-order allocations and saves quite a bit of memory. Phonet MTU is
65541 bytes, so the two buffers were padded to 128 kilo-bytes each.
Now, we create 17 page buffers, almost a 75% memory use reduction.

Convert the m66592-udc driver to use the on_chip flag
from platform data to enable on chip behaviour instead
of relying on CONFIG_SUPERH_BUILT_IN_M66592 ugliness.
This makes the code cleaner and also allows us to support
both external and internal m66592 with the same kernel.
It also makes the Kconfig part more future proof since
we with this patch can add support for new processors
with on-chip m66592 without modifying the Kconfig.
The patch adds a m66592 header file for platform data
and ties in platform data to the existing m66592 devices.

The reworked Ethernet gadget has an RNDIS interop problem when used
with the CDC subset driver ... e.g. on PXA 2xx and 3xx hardware,
which currently has a hard time talking to MS-Windows hosts.
The issue is that Microsoft requires USB_CLASS_COMM. Fix by tweaking
the CDC subset driver to not switch to USB_CLASS_VENDOR_SPEC if RNDIS
is used in some other device configuration.
