8b520ac153 clk: actions: Add common clock driver
This patch converts S900 clock driver to something common that can
be used for other SoCs, for instance S700(few of clk registers are same).

4939beea8e arm: dts: sync dts for Action Semi S900
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.

e25080664a clk: Remove DM_FLAG_PRE_RELOC flag in various drivers
When a driver declares DM_FLAG_PRE_RELOC flag, it wishes to be
bound before relocation. However due to a bug in the DM core,
the flag only takes effect when devices are statically declared
via U_BOOT_DEVICE(). This bug has been fixed recently by commit
"dm: core: Respect drivers with the DM_FLAG_PRE_RELOC flag in
lists_bind_fdt()", but with the fix, it has a side effect that
all existing drivers that declared DM_FLAG_PRE_RELOC flag will
be bound before relocation now. This may expose potential boot
failure on some boards due to insufficient memory during the
pre-relocation stage.

To mitigate this potential impact, the following changes are
implemented:

- Remove DM_FLAG_PRE_RELOC flag in the driver, if the driver
  only supports configuration from device tree (OF_CONTROL)
- Keep DM_FLAG_PRE_RELOC flag in the driver only if the device
  is statically declared via U_BOOT_DEVICE()
- Surround DM_FLAG_PRE_RELOC flag with OF_CONTROL check, for
  drivers that support both statically declared devices and
  configuration from device tree

ae485b540f clk: Add Actions Semi OWL clock support
This commit adds Actions Semi OWL family base clock and S900 SoC
specific clock support. For S900 peripheral clock support, only UART
clock has been added for now.
