stm32: f247: flash: use common code.

Browse Source 
This shows what is _actually_ different for f7.  A couple of option
bits, and a renaming of bit 7 of the status register, from Program
Sequence Error to Erase Sequence Error.

We keep the separate implementation of wait_for_last_operation, to meet
the "suggestions" of the reference manual to insert a DSB instruction.

Keeping the renamed bit/functions also requires us to keep separate
implementations of the flag clearing functions
