The Peripheral Web's PDM hardware block on several Qualcomm SoCs
contains a GP_MN clock divider that generates a fractional output
frequency from a fixed input clock (typically TCXO4):

  Fout = Fin * (M / N)

The output is routed to an external GPIO pin via a dedicated pin mux
function, making it useful as a reference clock for external devices.

The hardware uses three registers:
  - MDIV: holds M (9-bit numerator)
  - NDIV: holds the 1's complement of (N - M) (13-bit period)
  - DUTY: holds D, the low-phase count, constrained to M < D < (N - M)

This series adds full upstream support for the block:

  Patch 1: dt-bindings YAML schema for qcom,clk-gp-mnd
  Patch 2: standalone platform driver using rational_best_approximation()
           to find the closest M/N pair, with full clk_ops coverage
           (determine_rate, set_rate, recalc_rate, get_duty_cycle,
           set_duty_cycle) and AHB bus clock gating around register
           accesses
  Patch 3: gp_mn pin mux function for QCS8300, SA8775P and SC7280
           TLMM pin controllers
  Patch 4: pinctrl state nodes for the GP_MN output pin in the
           kodiak (SA8775P), lemans (SA8775P) and monaco (QCS8300)
           SoC device trees
  Patch 5: GP_MN clock controller DT nodes for SA8775P (kodiak,
           lemans) and QCS8300 (monaco), clocked from GCC PDM XO4
           and AHB clocks with the XO4 pre-assigned to 4.8 MHz
