Is your feature request related to a problem? Please describe.

The current compatible = "nxp,imx-flexspi-nor"; driver already supports the IS25WX01G flash driver, but not in Octal mode. Adding support would result in much higher read/write speeds.

Describe the solution you'd like

Add the custom bits to the driver to enable the octal mode for this particular controller. I fail to grasp the custom/JEDEC handling in the current driver to add the necessary updates myself.

An ideal situation would be something like what is described in #46399

Describe alternatives you've considered
