[PATCH v3 1/2] arm64: dts: qcom: sda660-inforce-ifc6560: fix ADV7535 interrupt parent

[Dmitry Baryshkov]

Probing the ADV7535 HDMI bridge fails on the IFC6560:

  gpio gpiochip3: (800f000.spmi:pmic@2:gpio@c000): gpiochip_lock_as_irq: tried to flag a GPIO set as output for IRQ
  gpio gpiochip3: (800f000.spmi:pmic@2:gpio@c000): unable to lock HW IRQ 10 for IRQ

The bridge's interrupt line, HDMI_INT_N, is wired to GPIO11 of the PM660,
not of the PM660L. PM660L GPIO11 is LPKs_CTRL, an output which the
bootloader drives high, so gpiochip_lock_as_irq() refuses to turn it
into an interrupt and requesting the interrupt fails.

Point the interrupt at the PM660 GPIO.
