staging: media: atomisp: reduce load_primary_binaries() stack usage

The load_primary_binaries() function is overly complex and has som large
variables on the stack, which can cause warnings depending on CONFIG_FRAME_WARN
setting:

drivers/staging/media/atomisp/pci/sh_css.c: In function 'load_primary_binaries':
drivers/staging/media/atomisp/pci/sh_css.c:5260:1: error: the frame size of 1560 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]

Half of the stack usage is for the prim_descr[] array, but only one
member of the array is used at any given time.

Reduce the stack usage by turning the array into a single structure.
