Move the function retrieving the format override information for a given
format/modifier to intel_fb.c. We can store a pointer to the format list
in each modifier's descriptor instead of the corresponding switch/case
logic, avoiding the listing of the modifiers twice.
v1: Unchanged.
v2: Handle invalid modifiers in intel_fb_get_format_info() passed from
userspace. (CI/igt_kms_addfb_basic/addfb25-bad-modifier)
v3: Move lookup_modifier() to the next patch, where it's first used.
