The driver is adapted from Linux kernel's version of clk-th1520-ap.c,
with only output clocks for external sensors, which are barely useful in
bootloaders, removed.

Same as the mainline driver, it currently lacks of ability to enable and
reconfigure PLLs, which could be implemented later.

Add support for Airoha AN7581 SoC clock driver. This mainly needed for
eMMC support to correctly get the current clock applied.

Based on the Linux clk-en7523.c but majorly reworked for U-Boot that
doesn't require CCF subsystem.

Major modification, support for set_rate, realtime get_rate and split
for reset part to a different driver.

Add a stub clock driver which can be used to bind clock controllers
which aren't required for the platform to boot, but which are needed for
U-Boot drivers to work.

In addition, add a NOP parent driver to allow for binding the parent
nodes of the clock.

Initially this driver supports a Qualcomm platform where the MMC driver
tries to fetch the RPM clock controller, which is not actually required
for the device to work.

Use PHASE_ as the symbol to select a particular XPL build. This means
that SPL_TPL_ is no-longer set.

Update the comment in bootstage to refer to this symbol, instead of
SPL_

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

This adds support for the SC5XX clock trees which are required for reading
clock speeds on the SoCs. This is largely a port of the same support for
Linux, which has not yet been submitted upstream.

Clock drivers don't belong here, move them to the right place and
declutter mach-snapdragon a bit.

To de-couple these drivers from specific "target" platforms, add
additional config options to enable each clock driver gated behind a
common CLK_QCOM option and enable them by default for the respective
targets. This will make future work easier as we move towards a generic
Qualcomm target.
