udev-toradex-rules: prevent mtd related errors
This prevents the following mtd related errors upon boot caused by the
systemd provided /lib/udev/rules.d/60-persistent-storage.rules:
[ 32.850265] I/O error, dev mtdblock0, sector 0 op 0x0:(READ) flags
0x80700 phys_seg 1 prio class 2
[ 32.868798] I/O error, dev mtdblock0, sector 0 op 0x0:(READ) flags
0x0 phys_seg 1 prio class 2
[ 32.883632] Buffer I/O error on dev mtdblock0, logical block 0, async
page read
[ 32.898644] I/O error, dev mtdblock0, sector 0 op 0x0:(READ) flags
0x0 phys_seg 1 prio class 2
[ 32.913332] Buffer I/O error on dev mtdblock0, logical block 0, async
page read
Add an additional rules file in
/etc/udev/rules.d/50-mtd-persistent-storage.rules to exclude mtd devices
from the persistent-storage rules processing.
