power: qcom: smb138x-charger: do not enable parallel thermal regulation
USB connector HW based thermal regulation is active which will throttle
the input current on USBIN-USBIN configurations. This was enabled for
MID-MID configurations to enable the comparator output for USB connector
temperature mitigation, but since the input is bypassed it does not
throttle the input current. The comparator output is no longer used
since the ADC values are used directly, so neither configuration needs
this HW feature to be enabled.
Remove the write to enable this HW feature.
