qcom-charger: qpnp-smb2: enable some irqs as a wakeup source 



Parallel charging requires the device to wake up when entering taper
charging state in order to reduce the parallel charger's FCC. Enable
the chg-state-change irq as a wakeup source.

Parallel charging requires the device to wake up when the USB ICL
changes in order to enable or disable. Enable the usbin-icl-change
irq as a wakeup source.

When a change is detected on the Type-C CC pins the device should wake
up to handle the change. Enable the type-c-change irq as a wakeup
source.

When VBUS is detected the device should wake up to adjust the state of
DP/DM to allow for proper APSD. Enable the usbin-plugin irq as a wakeup
source.

When APSD finishes the device should wake up to notify the USB, and PD
drivers. Enable the usbin-src-change irq as a wakeup source.
