Subject: [PATCH v4 07/15] arm64: dts: freescale: imx93-phyboard-segin: Disable SD-card write-protect

Add disable-wp flag (write-protect) to usdhc2 node (SD-card) to get rid
of the following kernel boot warning:

  host does not support reading read-only switch, assuming write-enable

Micro SD cards can't be physically write-protected like full-sized
cards anyways.
