This series adds support for the initial clock controllers required
by the upcoming Qualcomm Hawi SoC. These include the Global Clock
Controller (GCC), TCSR clocks, and RPMH-managed clocks. It also adds
the PLL support required by Hawi.

Changes in v3:
- Mark gcc_hawi driver data structures as const (no functional change).
- Link to v2: https://lore.kernel.org/r/20260409-clk-hawi-v2-0-c7a185389d9a@oss.qualcomm.com
Changes in v2:
- set the use_rpm flag for GDSCs to support runtime PM.
- Use clk_rcg_shared_ops instead of clk_rcg_shared_no_init_park ops
for the UFS RCGs. This avoids a UFS GDSC enable failure due to a
shared PLL used by the UFS RCGs being disabled while the RCGs are
still configured to it.
- Updated commit messages wording to explicitly refer to the chip as
the Qualcomm Hawi SoC.
- Collected Reviewed-bys
