ARM: dts: qcom: mdm9615: move PMIC interrupts to the board files

The interrupt of SSBI PMICs is routed to the SoCs GPIO. As such, it is
not a property of the SoC, it is a property of the particular board
(even if it is standard and unified between all devices). Move these
interrupt specifications to the board files.
