qpnp-smb2: allow parallel charging during supplemental mode

Browse source 
PMI8998 register 0x1690 BIT(2) is incorrectly documented. This bit enables
a feature to disable the parallel charger via STAT when the PMI is
supplementing a system load using the battery. This feature is not
recommended since SW is limiting the power that the parallel charger can
draw based on the input power available, and the default power
distribution ensures that 50% of the available input power is allocated to
the PMI. Disable this feature.
