[PATCH v2 2/2] arm64: dts: allwinner: a64: Add lradc node

[Luca Weiss]

Add a node describing the KEYADC on the A64.

Signed-off-by: Luca Weiss <luca@z3ntu.xyz>

Changes since v1:
 - Use a a64 compatible with a fallback to the a83t one (the A64 also
   uses a 3/4 voltage divider, as is the case with the A83T)
 - Correct the reg property (size 0x100 => 0x400)
