input: qcom-hv-haptics: Toggle RC_CAL_EN mode only for PM8350B

Browse Source 
The incorrect first cycle vibration issue is applicable only
for PM8350B PMIC. Hence, make the SW W/A to toggle the CAL_EN mode
from disabled to auto mode specific for PM8350B PMIC. Introduce
a "wa_flags" variable to handle the SW W/A in a cleaner way.
