Correct address for STM32F2 flash size register

There was a typo in the flash size register address for STM32F2. Change
to correct address. Verified against STM32F207 reference manual
(RM0033 Rev 5 section 33.2), and an STM32F217 chip.
Remove unsupported --device option to st-util

Setting the STLINK device with -d hasn't worked for some time, but
the STLINK_DEVICE environment variable works instead. Remove the
option, update documentation and help text.

When ignoring the end of a file, make sure we don't ignore partial words.

Consider a 128-byte write to the chip.  If the last 2 bytes are
considered "empty", then len is adjusted to 126, and run_flash_loader
will only copy 126 bytes to RAM.  However, run_flash_loader then
proceeds to round up to 32 words (128 bytes) when flashing, which has
the effect of clobbering those last two "empty" bytes with junk data.
