cc2538: upload: Support .bin not starting at beginning of flash

Browse source 
Depending on the linker script, the generated .bin file may start beyond
the beginning of the flash memory. However, no target address was passed
to cc2538-bsl.py by the upload make target, so it used the beginning of
the flash memory in all cases.

The load address of the lowest loadable output section is now passed to
cc2538-bsl.py. The start address of the .text output section or the
address of the _text symbol could have been used too, but this would not
have been compatible with all the possible custom linker scripts.
