Richard Meadows 98faaceb70 [efm32] Add support for EFM32 devices with different DI and MSC layouts

* DI layout is identified by attempting to read OUI from both layouts
* MSC address is passed to flashstub in r3

Retested EZR32LG230 (EZR Leopard Gecko M3)
Tested EFR32BG13P532F512GM32 (EFR Blue Gecko)

Achieves aims of PR #264 (I think) Thanks to @dholth and @ryankurte for inspiration
Fixes Issue #226

Flash Stubs

These are simple routines for programming the flash on various Cortex-M microcontrollers. The routines should be provided with the naked attribute as the stack may not be available, and must not make any function calls. The stub must call stub_exit(code) provided by stub.h to return control to the debugger. Up to 4 word sized parameters may be taken.

These stubs are compiled instructions comma separated hex values in the resulting *.stub files here, which may be included in the drivers for the specific device. The drivers call these flash stubs on the target by calling cortexm_run_stub defined in cortexm.h.
