Added some descriptions for missing parameters, (hopefully) clarified
some along the way. Fixed all can related warnings in doxygen logs.
Added doxgen tags where meaningful comments had been provided. Dropped
redundant comment separators.
Add stm32h7 support for FDCAN peripheral. Source level compatibility is
provided with stm32g4. Additional features of stm32h7 such as
configurable buffers are supported. Implementation offers feature parity
with stm32g4 implementation.
Add stm32g4 support for FDCAN peripheral. Normal / FDCAN operation
supported, bitrate switching and filtering supported via API.
Timestamping and transmit event buffer support in API are TBD.

Worked in nuances for differences between versions of STM32H7 devices, such as
handling of ODEN, explicit SCUEN bit, and different VOS mappings. This has
been validated on the STM32H7A3 and STM32H743 MCUs.
Old API required users to manually construct bit maps frm opaquely named
defines, with little help. It also was a pure OR operation, with no way
to ever clear bits.

Use a single @defgroup for the "root" of a common heirarchy, and only
addtogroup for additions. This prevents an alphabetically "first" entry
from being used as the documentation for the entire group.
We need per device header includes to make the per target documentation
generation work properly. The dispatch headers are to dispatch to the
_target_ not directly to the final implementation, remember, the final
required headers for each may be multiple files, plus extra definitions!
Allows for abstraction for code that's dependent on knowing the source clock
for a peripheral. Implemented a few core peripherals that tend to have clock
tree differences between platforms (USART, timers, I2C, SPI).
We still need stub .c files as we're using shared common files, so .d
tracking doesn't work. It lets us setup basic introductory text anyway,
and there will be .c files eventually, so acceptable.
Provide gpio examples for both f1 and "everyone else" gpio blocks

(Merged old and new into two new examples)
The random number generator on the STM32H7 is identical to the v1 RNG
already present in the library. So use that, and make sure that the RCC
knows about the peripheral.

While it doesn't work for everyone, this is clearly the basic first
steps required for any progress to be made.
