ARM: dts: mdm9640: Add clock nodes for apss and bimc axi 



When cpu attempts idle power collapse, system hangs
randomly. The signature of the hang is a pending write
on bimc port as soon as it exits from power collapse. To
recover from this condition, we need to enable hardware clock
gating of bimc/apps axi clk only for idle spc and pc.
