Depending on the considered baseboard the bit used to
reset the platform is different.
Here is the list of considered Realview/Versatile platforms:
Realview/Versatile AB for ARM926EJ-S: BOARD_ID = 0x100 = BOARD_ID_PB926
http://infocenter.arm.com/help/topic/com.arm.doc.dui0225d/CACCIFGI.html
RealView Emulation Baseboard: BOARD_ID = 0x140 = BOARD_ID_EB
No reset register
RealView PB for Cortex-A8: BOARD_ID = 0x178 = BOARD_ID_PBA8
http://infocenter.arm.com/help/topic/com.arm.doc.dui0417d/BBACIGAD.html
RealView PB for Cortex-A9: BOARD_ID = 0x182 = BOARD_ID_PBX
http://infocenter.arm.com/help/topic/com.arm.doc.dui0440b/CACCHBFB.html
Motherboard Express µATX: BOARD_ID = 0x190 = BOARD_ID_VEXPRESS
No reset register

v3:
- change patch name to something more meaningful
- move version information after the commit message.
- remove added BOARD_ID and code for unsuported board
- remove code style fixing for unrelated code
v2:
- Add multiple boards support
- fix coding style
- Added a BOARD_ID descriptor for unsupported baseboards.
