Introduce the initial set of clock controller bindings and driver
support for the upcoming Qualcomm Maili SoC.

Maili is a new mobile SoC from Qualcomm. It is a derivative of the
Hawi SoC and shares most of its clock topology. Where the hardware is
identical, Maili reuses the existing Hawi drivers via fallback
compatible strings. Where Maili diverges — specifically in the Global
Clock Controller (GCC), which carries an additional QUPv3 wrapper
(WRAP5) — the Hawi GCC driver is extended to handle both SoCs.

The series covers the following clock controllers:

  - RPMH clock controller: identical to Hawi; uses qcom,hawi-rpmh-clk
    as fallback.
  - TCSR clock controller: identical to Hawi; uses qcom,hawi-tcsrcc
    as fallback.
  - Global Clock Controller (GCC): extends the Hawi GCC driver with
    eight additional QUPV3 WRAP5 clocks present only on Maili.
  - CPUCP mailbox controller: software-compatible with X1E80100; uses
    qcom,x1e80100-cpucp-mbox as fallback.

The devicetree for Maili will be upstreamed later.

 Changes in v2:
  - Split the new Maili-only QUPv3 WRAP5 clock IDs out of
    qcom,hawi-gcc.h into a new qcom,maili-gcc.h header (which includes
    qcom,hawi-gcc.h), instead of adding them directly to the Hawi
    header. [Krzysztof]
  - Update the GCC driver to include the maili-gcc header.
