flash/nor/stm32f2x: Fix erase of bank 2 sectors
This commit corrects the erase function for stm32f2x when dealing with
sectors in bank 2, for STM32F42x/43x devices with 1MB flash.
On STM32F42x/43x with 1MB flash in dual bank configuration, the sector
numbering is not consecutive. The last sector in bank 1 is number 7, and
the first sector in bank 2 is number 12.
The sector indices used by openocd, however, _are_ consecutive (0 to 15
in this case). The arguments "first" and "last" to stm32x_erase() are of
this type, and so the logic surrounding sector numbers needed to be
corrected.
Since the two banks in dual bank mode have the same number of sectors, a
sector index in bank 2 is larger than or equal to half the total number
of sectors.
