[PATCH v3 01/18] media: allegro: nal-hevc: Replace array[1] with arrray[N]

[Ricardo Ribalda]

Structures that have a single element array as the last field can be
mistaken as a "flex array".

We could replace all the single element arrays in the structure with
single element fields, but this driver prefers to follow the ITU-T H.265
specification, which defines it as an array.

If we introduce a new define N_HRD_PARAMETERS, we make clear our
intentions.

This fixes this cocci warning:
drivers/media/platform/allegro-dvt/nal-hevc.h:102:14-22: WARNING use flexible-array member instead (https://www.kernel.org/doc/html/latest/process/deprecated.html#zero-length-and-one-element-arrays)
