usb: dwc3: add vendor prefix against used dwc3 flags

Browse source 
Currently there is no prefix used with dwc3 flags like
tx-fifo-size, host-only-mode, nominal-elastic-buffer and
core_reset_after_phy_init (rename as core-reset-after-phy-init).
This change adds snps as prefix to reflect that those are used
usb core vendor's feature. This change also makes required
changes with all devicetree files where it is applicable.
