dt-bindings: usb: Add compatible strings for s32g2/s32g3

Add the compatible strings for the NXP s32g2 and s32g3. These chips
are mostly compatible. The one difference is that the s32g2-usbmisc
device has an errata ERR050474 which requires a special flag to be set
for handling packages that aren't 4 byte aligned.
