mt76: fix broken airoha patches and remove 01_ECNT_MT76_220125_porting.patch
It looks like patches have been hand edited and the leading space has gone missing in various places. This was causing certain hunks to be ignored. Also remove duplicate diff for tools/CMakeLists.txt
Remove 01_ECNT_MT76_220125_porting.patch as all it does is cause eeprom to be loaded from /etc/Wireless/RT2860AP_AC/RT30xxEEPROM.bin and /etc/RT30xxEEPROM.bin instead of /lib/firmware/mediatek/mt7915_eeprom.bin and /lib/firmware/mediatek/mt7915_eeprom_2g.bin
Note that these two commits in combination do no effectively change behaviour as 01_ECNT_MT76_220125_porting.patch has always been broken and the part that actually changes the eeprom file location never applied.
