Subject: [PATCH v3 1/4] dt-bindings: usb: Add compatible strings for
 s32g2/s32g3

From: Ghennadi Procopciuc <ghennadi.procopciuc@....com>

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.
