Don't populate the read-only arrays on the stack but instead them
static const. Also makes the object code smaller by 154 bytes:
Before:
text data bss dec hex filename
42949 22424 0 65373 ff5d media/dvb-frontends/mb86a20s.o
After:
text data bss dec hex filename
42731 22488 0 65219 fec3 media/dvb-frontends/mb86a20s.o
(gcc version 11.2.0)
