Allow for write enable and sticky property
...
This commit adds new type of fields: sticky with write enable.
This is used to gate status/interrupt register when one or more
interrupts aren't monitored.

Remove unreachable code
...
According to the SystemRDL specification interrupt can be either:
level, posedge, negedge, bothedge, or nonsticky.
This means that it's impossible to reach create filed that
satisfies [Pos|Neg|Both]edgeNonstickybit match functions.
