New pwrap support int1_en flag for starvation and channel
request exception. We need to register it for interrupt
handler.
We also add pwrap capability flag used to declare if we
"We also" wording is nearly always a hint, that this should be done
in two independent patches.

support BRIDGE, RESET, DCM, PRIORITY_SEL and INT1_EN

As you told me the driver will be upstreamed in April, please add this flag when
you upstream the driver, as this will be in a different kernel version.

Add each flag when you add the user of the flag.

NAK, this will not compile. Please make sure that every patch on it's own does
not break compilation.
