ARM: dts: renesas: Drop most of bootph-* tags

The bootph-* tags are now part of mainline Linux DTs as commits:
f1a1268572cc ("ARM: dts: renesas: rcar-gen2: Add boot phase tags")
399f14ff6625 ("arm64: dts: renesas: rcar: Add boot phase tags")
624b2a23d46a ("arm64: dts: renesas: rzg2: Add boot phase tags")
Drop local duplicates of the same tags, as well as duplicate
property assignments which are part of the core DTs themselves.
