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
