SoC changes for omap variants for v5.2 merge window

This series of changes mostly consists of ti-sysc interconnect driver related preparation work. With these changes and the related ti-sysc driver changes, we can start dropping legacy omap_hwmod_*data.c platform data for many devices.

There are also two am335x and am437x related PM changes for secure devices that have ROM handling some parts and needs EFUSE power domain active.

Driver changes for ti-sysc for v5.2 merge window

This series of changes for ti-sysc interconnect target module driver gets us to the point where we can actually drop legacy platform data for many devices in favor of device tree data.

To do this, we improve ti-sysc driver not to rely on platform data callbacks to manage module clocks, and handle more quirks needed for some devices. Also few minor fixes are needed, but were considered not needed to be sent separately as they only show up with this series.

Then we drop several thousands of lines of legacy platform data for omap4, omap5, dra7, am335x and am437x. We drop platform data for mmc, i2c, gpio and uart devices to start with as those are typically easily tested on all devices. In case of unexpected issues, we can just add back the legacy platform data for a single device type if needed.

Finally we add initial support for enabling and disabling some devices without legacy platform data callbacks. I was planning on sending the dropping of legacy platform data as a separate series, but already applied Roger's patch on top and pushed it out.

Note that this series depends on related SoC and is based on those.

Merge branch 'omap-for-v5.2/am4-ddr3' into omap-for-v5.2/am4-pm-v2 (2019-04-10 09:06:01 -0700)

----------------------------------------------------------------
PM changes for am335x and am437x

This series adds support for am437x RTC-only mode in suspend. In the RTC-only mode suspend, everything is shut down except the RTC. This makes the power consumption very low for suspend mode.

To support RTC-only mode, we need to export omap_rtc_power_off_program() from the rtc driver and improve PM code to save and restore the wkup domain context. As RTC-only mode depends on the device being wired properly for things like memory, we need to also check for the machine type before we allow it. We also need to run DDR3 hardware leveling on resume.

Note that there is a trivial merge conflict between the RTC branch and these changes where the RTC branch makes tm2bcd() a void function and the error handling parts can be just dropped.
