regulator: qpnp-labibb: Don't handle LAB_VREG_OK in TTW mode for pmi8998

Browse Source 
Currently for pmi8998, LAB_VREG_OK interrupt is handled to switch
from PWM to PFM mode after a certain delay to improve efficiency.
Also, PFM mode is kept disabled once the regulator is disabled.
As per the hardware recommendation, keeping LAB in PWM mode is
sufficient in particular when TTW mode is enabled. Hence do not
register for LAB_VREG_OK interrupt in TTW mode so that this
PWM <-> PFM mode transition will not be done.
