Added support for DMA transfers. The implementation uses the user watermark
to decide whether DMA will be used or not. For watermark 1, DMA will not be
used. If watermark is bigger, DMA will be used.
Sysfs attributes are created to indicate whether the DMA is used,
with hwfifo_enabled, and the current DMA watermark is readable
in hwfifo_watermark. Minimum and maximum values are in hwfifo_watermark_min
and hwfifo_watermark_max.

Add necessary casting to several places where we were doing 32-bit
arithmetic (unsigned) to produce a 64-bit (unsigned long) result, to
prevent the theoretical possibility of a 32-bit overflow during the
arithmetic.

FYI, these are unsigned long:

	ctx->param_bytes
	ctx->allocbytes

These are unsigned int:

	bytes
	phdr->name_offset
	phdr->name_length

Here is the test program demonstrating why we really need the casts:

void main()
{
	unsigned int i;
	unsigned long il;

	printf("sizeof(int) =%dn",sizeof(i));
	printf("sizeof(long)=%dn",sizeof(il));

	i = (unsigned int)((((unsigned long)(1)) << 32) - 1);
	printf("i                     = %un", i);
	il = i+1;
	printf("adding 1 withOUT cast = %lun", il);
	il = (unsigned long)i+1;
	printf("adding 1 WITH    cast = %lun", il);
}
[selltc@mac tmp]$ gcc x.c -o x.out
[selltc@mac tmp]$ ./x.out
sizeof(int) =4
sizeof(long)=8
i                     = 4294967295
adding 1 withOUT cast = 0
adding 1 WITH    cast = 4294967296

The imx media driver passes around monotonic timestamps in the deprecated
'timespec' format. This is not a problem for the driver, as they won't
overflow, but moving to either timespec64 or ktime_t is preferred.

I'm picking ktime_t for simplicity here. frame_interval_monitor() is
the main function that changes, as it tries to compare a time interval
in microseconds. The algorithm slightly changes here, to avoid 64-bit
division. The code previously assumed that the error was at most 32-bit
worth of microseconds here, so I'm making the same assumption but add
an explicit test for it.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.

Update the android driver files with the correct SPDX license identifier
based on the license text in the file itself.  The SPDX identifier is a
legally binding shorthand, which can be used instead of the full boiler
plate text.

Ombredanne, and Kate Stewart.
