arm: dts: allwinner: drop underscore in node names

Underscores should not be used in node names (dtc with W=2 warns about
them), so replace them with hyphens.  Use also generic name for pwrseq
node, because generic naming is favored by Devicetree spec.  All the
clocks affected by this change use clock-output-names, so resulting
clock name should not change.  Functional impact checked with comparing
before/after DTBs with dtx_diff and fdtdump.
