power: smb-lib: cache USB Type-C status
Currently the USB Type-C status is retrieved from the hardware in real
time. The Type-C change IRQ should trigger on every change of the Type-C
status, therefore it is not necessary to read the status registers
multiple times if a Type-C change IRQ has not triggered. Furthermore,
workarounds which force UFP/DFP mode, or disable Type-C altogether could
mislead the software into thinking a removal has happened.
Cache all of the USB Type-C status registers upon receiving a USB Type-C
change IRQ, and use the cached status where appropriate.
