Ashok Reddy Soma 90f06e9d20 arm64: versal: Update mini u-boot eMMC node parameters
Mini u-boot eMMC dt parameters are not in sync with full u-boot dt.

Frequency for eMMC is fixed to 25Mhz. Due to this, mmc multi-block write
commands are failing. Increase frequency to 200Mhz to fix this issue.

Add bus-width = <8>, non-removable and disable-wp properties to the node
as this is eMMC.
