Debug console is the part of serial driver in the same file. It means to be
able to enable debug console you also need to enable driver itself.
That's why add all dependecies and list only debug consoles which are
enabled based on driver selection to avoid compilation error when user
asks for certain debug console but driver is not enable for it.

We cannot rely on a parent bus that needs to be probed, until we know that
it is probed. That means that code in the ofdata_to_platdata() method
cannot rely on the parent bus being probed.

Move the ofdata code in the two serial drivers into a probe() method.

This fixes serial output on rpi_3b_32b with the following config.txt
options:

   enable_uart=1
   gpu_freq=250

Even though the PL011 UART driver claims to be DM compliant, it does not
really a good job with parsing DT nodes. U-Boot seems to adhere to a
non-standard binding, either requiring to have a "skip-init" property in
the node, or to have an extra "clock" property holding the base
*frequency* value for the baud rate generator.
DTs in the U-Boot tree seem to have been hacked to match this
requirement.

The official binding does not mention any of these properties, instead
recommends a standard "clocks" property to point to the baud base clock.

Some boards use simple "fixed-clock" providers, which U-Boot readily
supports, so let's add some simple DM clock code to the PL011 driver to
learn the rate of the first clock, as described by the official binding.

These clock nodes seem to be not ready very early in the boot process,
so provide a fallback value, by re-using the already existing
CONFIG_PL011_CLOCK variable.

Synchronize device tree bindings with v5.5-rc6 tag with commit id
"b3a987b0264d".

Also, it removes older clock binding defined for S900 along with undocumented
compatible string "actions,s900-serial" from serial driver and adapts clock
driver to cater to new bindings.
