The digicolor platform has three UARTs, but the Kconfig.debug
file explicitly lists port zero as the one to be used for the
console, while not providing any default values.

This can get an automated randconfig build stuck in a loop

the physical address, this patch provides that number as
default, along with a reasonable default value for the virtual

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.
