This adds common capability parser for all supported Venus
versions. Having it will help to enumerate better the supported
raw formats and codecs and also the capabilities for every
codec like max/min width/height, framerate, bitrate and so on.

The problem is that in the error case, we've incremented the data ptr
but not decremented rem_bytes, and keep reading (presumably garbage)
until eventually we go beyond the end of the buffer.
Instead, on first error, we should probably just bail out. Other
option is to increment read_bytes by sizeof(u32) before the switch,
rather than only accounting for the ptype header in the non-error
case. Note that in this case it is HFI_ERR_SYS_INVALID_PARAMETER,
ie. an unrecognized/unsupported parameter, so interpreting the next
word as a property type would be bogus. The other error cases are
due to truncated buffer, so there isn't likely to be anything valid
to interpret in the remainder of the buffer. So just bailing seems
like a reasonable solution.

This is the implementation of HFI. It is charged with the
responsibility to comunicate with the firmware through an
interface commands and messages.
- hfi.c has interface functions used by the core, decoder
and encoder parts to comunicate with the firmware. For example
there are functions for session and core initialisation.
- hfi_cmds has packetization operations which preparing
packets to be send from host to firmware.
- hfi_msgs takes care of messages sent from firmware to the
host.
