arm64: dts: imx93-11x11-evk: add 12 ms delay to make sure the VDD_SD power off

To support SD3.0 mode, according to the SD spec, a clean power off
for the VDD_SD is keep the VDD_SD lower than 0.5V for at least 1ms.
On imx93 board, gate off the VDD_SD, it will cost about 10ms to see
the voltage change from 3.3v to 0.5v. So at least need to dealy 11ms
to make sure a clean power off and power on. Here add 12ms dealy.
