Subject: [PATCH 5.4 202/255] wifi: rt2x00: dont run Rt5592 IQ calibration on MT7620

From: Daniel Golle <daniel@...rotopia.org>

[ Upstream commit d3aad83d05aec0cfd7670cf0028f2ad4b81de92e ]

The function rt2800_iq_calibrate is intended for Rt5592 only.
Don't call it for MT7620 which has it's own calibration functions.
