Since kernel 5.11, the PXA I2C driver has been converted to generic I2C
recovery, which makes the I2C bus completely lock up if recovery pinctrl
is present in the DT and I2C recovery is enabled.
This effectively completely broke I2C on Methode uDPU and eDPU boards
as both of them rely on I2C recovery.
After a discussion upstream, it was concluded that there is no simple fix
and that the blamed upstream commit:
0b01392c18b9993a584f36ace1d61118772ad0ca ("i2c: pxa: move to generic GPIO
recovery") should be reverted.
I have sent the revert upstream, it should be merged soon so lets "fix"
OpenWrt as well.

This has been a part of modified upstream patch but got lost on major
kernel bump to 5.15, so bring it back.
