meta-ked-imx: linux-ktn: mx93.cfg: enable tmpfs support
This MR enables tmpfs support in Linux kernel for iMX93.
It's needed to get rid of following issues:
- an error message in dmesg:
tmpfs: Unknown parameter 'mode'
- to make particular tmpfs partitions specified in default /etc/fstab to be mounted during boot:
tmpfs /run tmpfs mode=0755,nodev,nosuid,strictatime 0 0
tmpfs /var/volatile tmpfs defaults 0 0
