Allow for the high frequency clock that controlls things such as the
main CPU to be switched over to USHFRCODIV2. This is a 24 MHz PLL
that is trimmed using clock recovery from the USB signal, and is
accurate to within 1% of 24 MHz.

This clock is the USB High Frequency PLL that gets trimmed based
on clock recovery. It is the most accurate PLL on the system,
assuming it is connected via USB.
Add the definition of this clock in preparation for being able
to switch to it.

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
USB. 120MHz never had any purpose, other than to match the f2 code it
was copied from. Drop them both. Remaining configs are all max speeds
for various F4 parts. Lower speeds are all custom
Fixes: 96d094af13 mk/genlink-config: provide LIBNAME in devices autogeneration
The initial fix had fixed the examples repo, but broke the tests and the
template repo. Restore the suffix properly.
This makes the generic rules workk happily regardless of whether the
linkerscript generation is being used or not.
Notably, in the examples repo, use of the linker script autogeneration
was retriggering library builds as LIBNAME was unset and therefore the
libraries lib<blank>.a couldn't be found.
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.
Make the names match the reference manuals properly, and add missing
names. Still a long way to go to unify across all families, but this is
at least closer.
here, it's a bit of a mess.. G0 flash controller does not really
match exsting feature split. IE it has instruction cache only ..
so, no flash_idcache.c as it. flash_common_f could be used, but
flash_unlock would not take care of option byte ?
prefetch, icache and lock is ok. I had no look at flash programming
or erase yet..
