ARM: dts: msm: Add PM8008 OCP interrupt support for lito/bengal

Add PM8008 OCP interrupt support for lito. The OCP interrupt is
delivered to the SoC from the MISC module of the PM8008 through
the TLMM GPIO45. Add the necessary configuration for TLMM GPIO45
and MISC peripheral. Also configure the "qcom-i2c-pmic" module as
an interrupt controller.
