Try to stop extending the clk_id or clk_names if there are
more and more new BASIC clocks. To get its own clocks by the
basic_clk_name of each power domain.
And then use basic_clk_name strings for all compatibles, instead of
mixing clk_id and clk_name.

The functions provided by infracfg misc driver have no other user except
the scpsys driver so move those into scpsys driver directly.
And then, remove infracfg misc driver which is no longer being used.
BTW, in next patch, we're going to extend the bus protection functions
with more customized arguments.

MT8192, MT8183 and MT6765 have more control steps of bus protection
than previous project. And there add more bus protection registers
reside at infracfg & smi-common.
Extend function to support multiple step bus protection control
with more customized arguments.
And then use bp_table for bus protection of all compatibles,
instead of mixing bus_prot_mask and bus_prot_reg_update.

Add power dt-bindings of MT8183.
Add an optional "mediatek,smi" property for phandle to smi-common
node for power controller.
Introduce properties for power domain sub nodes.

Try to list all the power domains of under power controller
node to show the dependency between each power domain directly
instead of filling the dependency in scp_soc_data.
And could be more clearly to group subsys clocks into power domain
sub node to introduce subsys clocks of bus protection in next patch.

You're right! I'll use dev_err_probe() instead if anyone is interested
in this series. Thank you!

For the bus protection operations, some subsys clocks need to be enabled
before releasing the protection, and vice versa.
But those subsys clocks could only be controlled once its corresponding
power domain is turned on first.
In this patch, we add the subsys clock control into its relevant steps.

For some power domains like vpu_core on MT8183 whose sram need to
do clock and internal isolation while power on/off sram.
We add a cap "MTK_SCPD_SRAM_ISO" to judge if we need to do
the extra sram isolation control or not.

Add power controller node and smi-common node for MT8183
In scpsys node, it contains clocks and regmapping of
infracfg and smi-common for bus protection.
And list all the power domains of MT8183 under scpsys node
to show the dependency between each other through hierarchical
structure.
