650f867b1c Add a single-column variant to gpio_rcc! macro table 
which includes just the set of registers that need to be
considered.

Then match against those registers with a single `modify(...)`

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.

2f08c7ced5 stm32: Allow for RccPeripheral without reset field

RccPeripheral::reset a no-op on peripherals where a reset field couldn't
be found
