power: qpnp-bms: disable sw_cc_thresh interrupt after it fires

Currently in the BMS driver, when the software coulomb counter threshold
is reached, only a soc recalculation is scheduled in the irq handler.
This can cause issues where the BMS hardware fires another sw_cc_thresh
irq because the coulomb counter is still over threshold.

Instead, disable the sw_cc_thresh irq when it is handled and renable it
after adjusting the software coulomb counter threshold registers.
