media: i2c: dw9719: Fix power on/off sequence ...
The "jiggle" code was not actually expecting failure, which it should
because that's what actually happens when the device wasn't already woken
up by the regulator power-on (i.e. in the case of a shared regulator).
Also, do actually enter the internal suspend mode on shutdown, to save
power in the case of a shared regulator.
Also, wait a bit longer (2x tOPR) on waking up, 1x is not enough at least
on the DW9718S as found on the motorola-nora smartphone.
