soc: imx: imx93-pd: No need to set device_driver owner

There is no need to exclusively set the .owner member of the struct
device_driver when defining the platform_driver struct. The Linux core
takes care of setting the .owner member as part of the call to
module_platform_driver() helper function.

Issue identified using the platform_no_drv_owner.cocci Coccinelle
semantic patch.
