This series improves the RISC-V timer driver to set CLOCK_EVT_FEAT_C3STOP
feature based on RISC-V platform capabilities.

These patches can also be found in riscv_timer_dt_imp_v5 branch at:
https://github.com/avpatel/linux.git

Changes since v4:
 - Update commit text of PATCH1 based on Samuel's comments
 - Renamed DT property "riscv,timer-can-wake-cpu" to
   "riscv,timer-cannot-wake-cpu" in PATCH2 and PATCH3
 - Updated description of DT property "riscv,timer-cannot-wake-cpu"
   in PATCH2

Changes since v3:
 - Rebased on Linux-6.1-rc7
 - Replaced PATCH1 with a patch to initialize broadcast timer

Changes since v2:
 - Include Conor's revert patch as the first patch and rebased other patches
 - Update PATCH2 to document bindings for separate RISC-V timer DT node
 - Update PATCH3 based on RISC-V timer DT node bindings

Changes since v1:
 - Rebased on Linux-5.19-rc8
 - Renamed "riscv,always-on" DT property to "riscv,timer-can-wake-cpu"
