FROMLIST: arm64: dts: qcom: Add GP M/N clock controller node for SA8775P and QCS8300

Add the GP M/N divider clock controller node at 0x088d3000 to the
SA8775P (sc7280, lemans) and QCS8300 (monaco) SoC device trees.

The node uses the qcom,clk-gp-mnd compatible, is clocked by the PDM
XO4 and AHB clocks from GCC, and exposes a single clock output
(gp_mn_clk) on the dedicated gp_mn pin mux function. The XO4 clock
is pre-assigned to 4.8 MHz (XO/4).
