[PATCH] mt76: mt76x0e: make array mt76x0_chan_map static const, makes object smaller

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

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)
