[PATCH v4 0/3] add support for clocks on MT7981 SoC

[Daniel Golle]

The MediaTek MT7981 SoC is quite similar to its big sibling, the
MT7986. Hence most drivers can be reused and not much is missing the
get also this SoC working on mainline Linux.

Start with a cleaned-up version of the clock drivers, based on what can
also be found in MediaTek's SDK[1].

Upon request of AngeloGioacchino Del Regno this series has been rebased
and adapted to be applied on top of the pending series
"MediaTek clocks cleanups and improvements"[2]

The complete tree used for testing (with still some to-be-cleaned-up
changes, esp. for the Ethernet driver) can be found on Github[3].

Changes since v3:
 * fixed typos in commit descriptions

Changes since v2:
 * rebase on top of next-20230120 with v4 of AngeloGioacchino's series[2]
 * fix titles of dt-bindings commits (this time for real)
 * convert clk-mt7981-infracfg to use mtk_clk_simple_probe
 * make use of PLL_AO flag in clk-mt7981-apmixed
 * convert clk-mt7981-ethsys into platform driver, also using the generic
   probe function, allow building as module

Changes since v1:
 * rebase and adapt on top of [2]
 * split-off addition of dt-bindings header, fix filename
 * changed commit title as requested
