asoc: mbhc: enable l_det_en bit

Browse Source 
enable l_det_en bit while detecting the HS.

Issue: While removing HS some additional electrical interrupts
are triggered and reporting different events to userspace, which is
cause issues. To avoid this electrical interrupt flow, there is
a check in adc_hs_rem_irq for wcd_swch_level_remove() to check
for l_det_en bit status. Depends on this it will return from the
adc_hs_rem_irq() without going further.

Solution: Enabling the l_det_en bit will helps to avoid serving
electrical interrupt flow to further in adc_hs_rem_irq().So this
will helps to stop reporting different/unwanted events to user space.
