ARM: dts: msm: enable HSIC interrupt as wake up capable for 8926

HSIC strobe gpio line(#119 for 8926) is routed to MPM for waking
up MSM upon HSIC peripheral connection and remote wakeup. To achieve
this add HSIC interrupt to the MPM wakeup capable list.

Here 8926 & 8226 targets using the same PM DT file. But HSIC gpio
numbers are different for these two targets i.e 8226(#115) & 8926(#119).
Instead of re-spin the new PM DT file for 8926, override the gpio
mapping in msm8926.dtsi file.
