rcc_osc_bypass_enable and rcc_osc_bypass_disable have been copy/pasted
around for the last time! There's a compile bit to check for L0/L1, but
otherwise this is just code duplication for no gain.
Originally suggested in https://github.com/libopencm3/libopencm3/pull/399
At least provide macros for each family that allows easy masking of the
full set of reset reason flags. Trying to provide a function that
provides these in random upper bits seems unclear at best.
Add clock config for the 25MHz crystal found on the discovery board.
Verified to work on the STM32F7-Disco.

Modified namespaces and types->structs to avoid namespace pollution as
was fixed for other families in:

Most changes are noise from doxygen.
Readme udpated to explain newer FP_FLAGS for m7
stm32f7 library is skipped if the toolchain doesn't support it yet.
