stm32: add flash programming support
Implements the on-chip flash erasing and writing functions.
The actual writing is done from a routine in internal RAM (using the
special .iram.text section) with interrupt disabled as we cannot read
flash during the writing process.
The write-protect feature is only lightly tested.

BUG=chrome-os-partner:8865
TEST=run on Daisy, from the EC console, use flasherase and flashwrite
commands and observe the results using rw command.
