drm/bridge: make a const array static, makes object smaller

Don't populate the const array frs_limits on the stack but instead make
it static. Makes the object code smaller by 128 bytes:

Before:
text data bss dec hex filename
24845 7440 64 32349 7e5d ./drivers/gpu/drm/bridge/tc358768.o

After:
text data bss dec hex filename
24749 7408 64 32221 7ddd ./drivers/gpu/drm/bridge/tc358768.o

(gcc version 10.2.0)
