Regular rng peripheral, with one additional bit : clock error detection
apparently available on l4 chips). Curiously, Clock error detection is
_disabled_ when bit is set, but bit is cleared by default, so peripheral
/ clock error detection behaves like all other chips..
NB: RNG need proper rcc_ccicr_rngsel bits set to work, no clock is set by
default. Note also that on that chip fRNGCLK must be higher than fHCLK/32
doxygen really wants the @defgroup _and_ the @addtogroup to both have
the full name, matching identically, to avoid all warnings.
Standardize on the "CAPS_PERIPH peripheral API" style.
The leading - makes it rather inconsistent with the majority of other
projects around the world. Use the form everyone else uses.
To solve this, properly pass prefix to inner makes as was always
intended.

FLASH_CR_OPTSTRT needs to be written to FLASH_CR, and there is no reason
to mask the last two data bits.

(original code appeared to be badly copied from the flash_common_f24 codebase)
According to RM0351 and RM0394 flash needs to be programmed by double words.
Also fix flash_program() which was wrong anyways.

48Mhz has no purpose other than to be a naiive method of haivng working

Some families had partially moved to peripheral api, and others were
only documenting common code, but not specific code. Delete dummy .c
files, and check that all specific apis are also being documented, not
just common apis.
Functions that are already documented in the top level common api.h file
won't add any more documentation from later .c files. Keep docs for
part specifics, in the .h files where they're accessible to IDEs and
also the documentation generation, and drop all (including the redundant
ones) from the .c file.
the group defaults to the implicit container based on location, so drop
all the explicit @ingroups, less to maintain. Properly use /**@}*/ to
close all groups too, even though it mostly seems to have worked anyway.
Properly close all groups opened for files.
