In pmr735d_a.dtsi, the peripherals are added under the parent phandle
"spmi_bus", which was commonly used in older SoCs having only a single
bus under the PMIC arbiter, but in Kaanapali, there are two buses
present under the PMIC arbiter, with phandles "spmi_bus0" and "spmi_bus1",
so we cannot include the file as it is.

Thanks,
Jishnu
