This patch exports all auxiliary buffers, including SRAM, as debugfs binary

doesn't seem to be used at all on CODA7541, and that slicebuf and workbuf
usage is far from the maximum. It can also be used to validate SRAM size

When encoding into h.264, the input frame stride needs to be a multiple of 16.
During allocation of the input buffers, it may not be known yet whether the

Even though the CODA h.264 decoder always decodes complete macroblocks, we can
set the stride to the corresponding multiple of 16 and use a value smaller than
that as real width. Unfortunately the same doesn't work for height, as there
is no vertical linesperframe stride for discontiguous planar YUV frames.

This patch adds support for the CODA960 VPU in Freescale i.MX6 SoCs.
It enables h.264 and MPEG4 encoding and decoding support. Besides the usual
register shifting, the CODA960 gains frame memory control and GDI registers
that are set up for linear mapping right now, needs ENC_PIC_SRC_INDEX to be
set beyond the number of internal buffers for some reason, and has subsampling
buffers that need to be set up. Also, the work buffer size is increased to
80 KiB.
The CODA960 firmware spins if there is not enough input data in the bitstream
buffer. To make it continue, buffers need to be copied into the bitstream as
soon as they are queued. As the bitstream fifo is written into from two places,
it must be protected with a mutex. For that, using a threaded interrupt handler
is necessary.

Remove the CONFIG_ prefix from two Kconfig symbols in a dependency for
SMS_SIANO_DEBUGFS. This prefix is invalid inside Kconfig files.
Note that the current (common sense) dependency on SMS_USB_DRV and
SMS_SDIO_DRV being equal ensures that SMS_SIANO_DEBUGFS will not
violate its constraints. These constraint are that:
- it should only be built if SMS_USB_DRV is set;
- it can't be builtin if USB support is modular.
So drop the dependency on SMS_USB_DRV, as it is unneeded.
