* Deprecate calling .viewAs on non-hardware (#3395)

It's an error in most cases already, and in the cases it isn't, make it
a warning. Also fix a crash that could occur when viewing a non-Data
containing non-hardware Data.

Change what DataView allows in its type checking to enable Reset to be
viewed as either a UInt<1> or an AsyncReset.  This enables more flexible
DataViews which match already allowable Chisel and FIRRTL connection
semantics.
