Enabling sensor on Press is slow and frequent on/off
switching on Press/Release leads to unexpected results.
Looking into Kernel, the purpose of FOD_ENABLE/FOD_DISABLE
commands are to save battery. (ts->lowpower_mode) It is not
meant to handle fingerprint authentication on Press/Release.
It is expected that FOD is in ENABLED state whenever the user
is EXPECTED to use fingerprint authentication soon.
Thus, this patch moved FOD_ENABLE/FOD_DISABLE from
OnPress/onRelease to onShowFODView/onHideFODView so the
fingerprint authentication can be faster and the logic makes
more sense.
