The atomisp_set_fmt() function has multiple copies of the large
v4l2_format structure on its stack, resulting in a warning about
excessive stack usage in some rare randconfig builds.

drivers/staging/media/atomisp/pci/atomisp_cmd.c:5600:5: error: stack frame size of 1084 bytes in function 'atomisp_set_fmt' [-Werror,-Wframe-larger-than=]

Of this structure, only three members in the 'fmt.pix' member are
used, so simplify it by using the smaller v4l2_pix_format structure
directly. This reduces the stack usage to 612 bytes, and it could
be reduced further by only storing the three members that are used.

The currently used functions for converting the transmission mode and guard
interval from the internal values to the DVBv5 API values do not return
correct values for ISDB broadcasts:

- The raw (debugfs) transmission mode is an integer whose values can be
1, 2 or 3, that corresponds to 2K, 4K and 8K FFT modes respectively.
However sms_to_mode() expects values 2, 4 or 8.
- Guard interval, as defined by smscoreapi.h returns "1 divided by value"
instead of 0, 1, 2, and 3 as defined in sms_to_guard_interval_table().

This commit implements ISDB-T specific methods for converting the internal
values for the aforementioned parameters to the DVBv5 API values. It also
adds support for reporting FEC and time interleaving values for each one
of the layers.

There are certain expressions in a condition in atomisp, where a boolean
variable is compared with true/false in forms such as (foo == true)
or (false != bar), which does not comply with the coding style rule by
checkpatch.pl (CHK: BOOL_COMPARISON), according to which the boolean
variables should be themselves used in the condition, rather than
comparing with true or false.

E.g. In drivers/staging/media/atomisp/pci/atomisp_compat_css20.c:

if (asd->stream_prepared == false) {

Can be replaced with:
if (!asd->stream_prepared) {
