ramips: fix MTK_SOC for RT3662 devices

rt3883.mk contains both RT3662 and RT3883 device profiles, but commit
6a104ac77206 set MTK_SOC to rt3883 for all devices. This patch fixes it,
and renames dts files accordingly. And SoC compatible strings are also
appended in the dts.

Fixes: 6a104ac77206 ("ramips/rt288x,rt3883: Name DTS files based on scheme")
