ipq40xx: 5.15: fix ar40xx driver
Also apply commitab7e53e5cc
("ipq40xx: 5.10: fix ar40xx driver") to 5.15 driver. The commit fixes the data corruption on TX packets. Packets are transmitted, but their contents are replaced with zeros. This error is caused by the lack of guard (50 ms) intervals between calibration phases. This error is treated by adding mdelay(50) to the calibration function code. In the original qca-ssda code, these mdelays were existing, but in the ar41xx.c they are gone. Fixes:87318eb179
