power: smb-lib: WA to fix legacy cable detection

Currently a legacy cable is always assumed which causes decreased
performance from non-legacy HVDCP adapters with 10k ohm Rp.

Fix this by disabling and re-enabling Type-C to rerun the legacy cable
detection.

Moreover, the legacy cable IRQs are not used and cause unnecessary
type-c-change IRQs to fire. Disable them.
