Don't populate the array mt76x0_chan_map on the stack but instead make it
static const. Makes the object code smaller by 80 bytes.
Before:
text data bss dec hex filename
7685 1192 0 8877 22ad mediatek/mt76/mt76x0/eeprom.o
After:
text data bss dec hex filename
7541 1256 0 8797 225d mediatek/mt76/mt76x0/eeprom.o
(gcc version 9.2.1, amd64)
