[PATCH V3 4/4] arm64: dts: allwinner: h700: Add Anbernic RG35XX-SP

[Chris Morgan <macroalpha82@gmail.com>]

From: Chris Morgan <macromorgan@hotmail.com>

The Anbernic RG35XXSP is almost identical to the RG35XX-Plus, but in a
clamshell form-factor. The key differences between the SP and the Plus
is a lid switch and an RTC on the same i2c bus as the PMIC.
