Draft: meta-ked-imx: linux-ktn: mx93.cfg: Enable edma driver

Mikhail Vaniulin requested to merge feature/mx93-support-dev-lpspi-dma into feature/mx93-support

A following warning message can be found in dmesg during boot:

fsl_lpspi 44370000.spi: dma setup error -19, use pio

There are two causes of it:

  • dma is not enabled for lpspi2 node in device tree;
  • corresponding DMA driver for iMX93 is not enabled in the kernel config.

The current MR addresses the problem with Kernel config. And adjustment of device tree is done in another MR: sw/misc/linux!147 (closed)

Note: while these changes help to get rid of this warning, they may not be really needed at the end. Because the EERAM device, which is on lpspi2, is still not able to start.
