This change adds missing planar and semiplanar
formats from gb specification.
Mbus to Gb format map:
V4L2_MBUS_FMT_NV12_1x8 -> 0x12
V4L2_MBUS_FMT_NV21_1x8 -> 0x13
V4L2_MBUS_FMT_YV12_1x8 -> 0x16
V4L2_MBUS_FMT_YU12_1x8 -> 0x17
Change depends on:
"media: add new mediabus format enums for ara camera"

Interface has been changed.
return code will not return number of configured streams but
just error code.
Number of streams is passed as pointer and if operation result
is changed number of streams will be updated.
Flags are also used for information regarding configure stream
operation result.

And return the response num_streams field through a pointer variable
instead of using the return value of the function as both an error code
and a positive number of streams, it makes the API more consistent.

Provide a new function, gb_hd_output() to send data to the apbridge.
This is useful for the camera and audio drivers that need to do this
type of messaging.
The camera driver is converted to use this new function, the audio
driver can use it when it gets merged later.

The debugfs interface will be kept for module testing purpose in order
to exercise all the protocol operations with various valid and invalid
