RK3326: route the Soysauce PMIC interrupt to GPIO0_A7

Browse Source 
Live debugging showed the whole rk817 interrupt line dead on the
Soysauce (zero counts in /proc/interrupts for pwrkey, jack and charger
events across button presses). The vendor DTB wires pmic_int to
GPIO0_A7 while the shared r3xs.dtsi listens on GPIO0_B2, so every PMIC
interrupt was lost: power key, headphone detect, charger plug and the
suspend wake source. Override the interrupt and the pinctrl in the
soysauce DTS only; the other family members really use GPIO0_B2.
