stm32f2x: Fix left shift of negative value 

Use unsigned constant for left shift operation in order to avoid the
following error with GCC >= 6.0:

../src/flash/nor/stm32f2x.c: In function ‘stm32x_handle_unlock_command’:
../src/flash/nor/stm32f2x.c:1324:67: error: left shift of negative value [-Werror=shift-negative-value]
   stm32x_info->option_bytes.optcr2_pcrop = OPTCR2_PCROP_RDP | (~1 << bank->num_sectors);
