stm32l4_work_area struct is shared between the loader and stm32l4x flash driver
'*wp' and '*rp' pointers' size is 4 bytes each since stm32l4x devices have
32-bit processors.
however when used in openocd code, their size depends on the host
if the host is 32-bit, then the size is 4 bytes each.
if the host is 64-bit, then the size is 8 bytes each.
to avoid this size difference, change their types depending on the
usage (pointers for the loader, and 32-bit integers in openocd code).
