In some board device tree files, "rk805" was used for the RK805 PMIC's
node name. However the policy for device trees is that generic names
should be used.

Replace the "rk805" node name with the generic "pmic" name.

Fixes: 1e28037e ("arm64: dts: rockchip: add rk805 node for rk3328-evb")
Fixes: 955bebde ("arm64: dts: rockchip: add rk3328-rock64 board")
