b64f51c4ad pm2301-charger: Wake device on register access
When USB  Dedicated or Standard host chargers are plugged into
the device, chargealg attempts to disable the PM2301 AC charger,
However, disabling PM2301 was failing because of it being in
runtime suepend mode & LPN pin being low.

aee2b8468c pm2301-charger: Add pm_runtime_resume & pm_runtime_suspend
To optimize the current consumption we use pm_runtime autosuspend
functions which execute the pm_runtime_suspend after a delay of
inactivity on the other hand we use pm_runtime_resume every time
we receive an interruption to wake up the pm2301.
