firmware: turris-mox-rwtm: add marvell,armada-3700-rwtm-firmware compatible string

Add more generic compatible string 'marvell,armada-3700-rwtm-firmware' for
this driver, since it can also be used on other Armada 3720 devices.

Current compatible string 'cznic,turris-mox-rwtm' is kept for backward
compatibility.
