Merge pull request #310 from bobmcwhirter/dbg 
Add a `Dbgmcu` struct capable of enabling all relevant DBGMCU.cr fields.

d68f2617e6 Add a Dbgmcu struct capable of enabling all relevant DBGMCU.cr fields. 
Includes the addition of a `dbgmcu!(...)` macro table which currently takes
the form of

	(cr, $fn_name:ident)

where `$fn_name` is something like `set_dbgsleep_d1` etc.

The method is unsafe, since it's performing unsafe PAC operations.

Two examples modified to demonstrate its usage.
