[PATCH v5 1/4] media: dt-bindings: rockchip,vdec: Mark reg-names required for RK35{76,88}

[Cristian Ciocaltea]

The Rockchip Video Decoder driver expects reg-names to be mandatory for
RK3576 and RK3588 SoCs, however the binding does not currently require
the use of them.

As a consequence, driver would fail to probe with a hypothetical
devicetree that doesn't provide the reg-names for these SoCs, but which
is otherwise a perfectly valid DT from the binding perspective.

Update the binding and make reg-names required for the aforementioned
SoCs.  While this change introduces an ABI break, the expected impact on
potential users would be minimal, if any, since the old SoCs are
unaffected, while the video decoder support for these newer variants in
mainline driver and devicetrees hasn't been released yet.

Moreover, this is also a prerequisite for a subsequent binding update
introducing an alternative reg-names order, according to the
address-based listing in the vendor's datasheet.
