power: smb135x-charger: use only usbin_uv/_ov for removal



The current driver uses both a falling edge on src_detect interrupt
or a rising edge on usbin_uv/_ov to initiate USB removal
activities. The src_detect is seen dropping even when a valid USB
is present.

Hence update the driver to use only usbin_uv/_ov interrupts for
USB removal.
