mt76: mt7921: set EDCA parameters with the MCU CE command

[ Upstream commit 66ca1a7b2d5503f561b751abdd6ec6fa96343eb6 ]

The command MCU_EXT_CMD_EDCA_UPDATE is not fully supported by the MT7921
firmware, so we apply CE command MCU_CE_CMD_SET_EDCA_PARAMS instead which
is supported even in the oldest firmware to properly set up EDCA parameters
for each AC.
