[PATCH 1/1] staging: vc04_services: Use %p4cc format modifier to print FourCC codes

Tue Oct 24 23:07:17 PDT 2023
Drop VCHIQ_FOURCC_AS_4CHARS macro in favour of %p4cc format
modifier to print FourCC codes in the logs.
vchiq_use_internal() and vchiq_release_internal() uses entity
character-array to store a transient string that contains
a FourCC code. Increase the length of entity array(to 64 bytes)
since %p4cc requires more bytes to hold the output characters.
