TI sysc driver changes for v4.20 merge window

This series gets rid of the SYSC_QUIRK_RESOURCE_PROVIDER to make device
detection happen mostly only if #define DEBUG is set. Few core devices still
need to be detected to set legacy quirks.

We also add support for booting am335x, am437x and dra7 SoCs with L4 devices
defined in device tree instead of legacy platform data.

And finally we simplify suspend with just SET_NOIRQ_SYSTEM_SLEEP_PM_OPS
and dropping the custom functions that were attempting to work around
issues that really turned out to be child device driver related issues.

Apologies for a late pull request, debugging the suspend issues took a while
and I did not want to send these changes until that got sorted out.

SoCs like AM43XX lose clock registers context during RTC-only
suspend. Hence add functions to save/restore the clock registers
context.

The clock gate restore context function enables or disables
the gate clocks based on the enable_count. This is done in cases
where the clock context is lost and based on the enable_count
the clock either needs to be enabled/disabled.

Deep enough power saving mode can result into losing context of the clock
registers also, and they need to be restored once coming back from the power
saving mode. Hence add functions to save/restore clock context.

The change in the DTS data node naming prevents using underscore
within the node names and force usage of dash instead. On the other
hand, clockdomains use underscore instead of dash, so this must be
replaced within the driver code so that the mapping between the two
can be done properly.

Currently, only one clkctrl node can be added under a specific CM node
due to limitation with the implementation. Modify the code to pick-up
clockdomain name from the clkctrl node instead of CM node if provided.
Also, add a new flag to the TI clock driver so that both modes can
be supported simultaneously.

As Grygorii Strashko pointed out, the runtime PM use count of the
children can be whatever at suspend and we should not use it. So
let's just suspend ti-sysc at noirq level and get rid of some code.

Let's also remove the PM_SLEEP ifdef and use __maybe_unused as the
PM code already deals with the ifdefs.
