Your description reminded me of a similar issue we hit with SPI transfer.
Back then Sascha fixed it but with some open question marks.

See 9da7e18573c725eaa6123c401df57d6a4f6a0ea2
("spi: i.MX: reset controller on init")

But as this is the latest patch to the imx_spi.c file you likely
have already looked at it.
But mentioned just in case..
