commit a11db8d8b403eba1f82728f440727128e9997edd upstream.

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.

With the introduction of the RK3588 SoC, and RK3576 afterwards, three register blocks have been provided for the video decoder unit instead of just one, which are further referenced in vendor's datasheet by 'link table', 'function' and 'cache'. The former is present at the top of the listing, starting at video decoder unit base address. However, while documenting RK3588, the binding broke the convention expecting the unit address to indicate the start of the primary register range, i.e. the 'function' block got listed before the 'link' one. Since the binding changes have been already released and a fix would bring up an ABI break, mark the current 'reg-names' ordering as deprecated and introduce an alternative 'link,function,cache' listing which follows the address-based ordering according to the TRM. Additionally, drop the 'reg' description items as the order is not fixed anymore, while the information they offer is not very relevant anyway. It's worth noting there are currently no (known) users impacted by these binding changes, since the video decoder support for the aforementioned SoCs in mainline driver and devicetrees hasn't been released yet - it landed in v7.0-rc1 while all DTS updates resulting from this will be handled before v7.0 is out.
