media: mxl692: make a const array static, makes object smaller
Don't populate the const array fw_hdr on the stack but instead it
static. Makes the object code smaller by 5 bytes:
Before:
text data bss dec hex filename
31948 12072 64 44084 ac34 drivers/media/dvb-frontends/mxl692.o
After:
text data bss dec hex filename
31879 12136 64 44079 ac2f drivers/media/dvb-frontends/mxl692.o
(gcc version 10.3.0)
