Driver changes for omaps for genpd support for v5.13

In order to move omap4/5 and dra7 to probe with devicetree data and genpd,
we need to patch the related drivers to prepare.

These are mostly ti-sysc interconnect target module driver changes and soc
init changes. However, there are minor changes to other drivers too. There
are changes for pci-dra7xx probe, omap-prm idle configuration, and a omap5
clock change:

- ti-sysc needs iorange check improved when the interconnect target module
  has no control registers listed

- ti-sysc needs to probe l4_wkup and l4_cfg interconnects first to avoid
  issues with missing resources and unnecessary deferred probe

- ti-sysc debug option can now detect more devices

- ti-sysc now warns if an old incomplete devicetree data is found as we
  now rely on it being complete for am3 and 4

- soc init code needs to check for prcm and prm nodes for omap4/5 and
  dra7

- omap-prm driver needs to enable autoidle retention support for omap4

- omap5 clocks are missing gpmc and ocmc clock registers

- pci-dra7xx now needs to use builtin_platform_driver instead of using
  builtin_platform_driver_probe for deferred probe to work

There are also few minor non-urgent fixes:

- soc init code pdata_quirks_init_clocks should be static

- ti-sysc has few unneeded semiconon typos

- ti-sysc can use kzalloc instead of kcalloc for a single element

Devicetree changes for omaps for genpd support for v5.13

In order to move omap4/5 and dra7 to probe with devicetree data and genpd,
we need to add the missing interconnect target module configuration for
the drivers that do not still have it. This is similar to what we have
already done earlier for am3 and 4 earlier.

These patches are very much similar for all the three SoCs here. The dra7
changes were already available for v5.12 merge window, but were considered
too late to add for v5.12. The patches for omap4 and 5 follow the same
pattern, except for PCIe that is available only on dra7.

We do the changes one driver at a time, and still keep the legacy property
for "ti,hwmods" mostly around, except for cases when already not needed.
We will be dropping the custom property and related legacy data in a
follow-up series.

  bus: ti-sysc: Warn about old dtb for dra7 and omap4/5 (2021-03-12 10:23:48 +0200)

----------------------------------------------------------------
Drop legacy data for dra7 and omap4/5 for genpd support for v5.13

Similar to what we have already done for am3 and 4, we can now boot dra7,
omap4, and omap5 with devicetree data and genpd without legacy SoC specific
built-in data.

Let's drop the legacy data for these SoCs, and the related "ti,hwmods"
custom devicetree property. As with these changes we now expect to have
complete devicetree data, let's also warn in the case if an old devicetree
data is noticed. And with the warning provided, there should not be any
need to delay dropping the legacy data as it just unnecessarily complicates
things.

The main reasons for dropping the legacy data is to avoid the burden of
maintaining a mixed boot process where both legacy built-in data and
devicetree data are needed. And we can now use standard reset driver,
genpd, and simple-pm-bus features.

These patches are based on the related devicetree changes to add the
missing interconnect target module configuration for these SoCs.
