ARM: SAMSUNG: Use local definitions of watchdog registers
This patch adds local definitions of required watchdog registers and bitfields to the uncompress header, allowing to remove the dependency on plat/regs-watchdog.h header and the ugly hack to replace virtual with physical addresses. In addition, it fixes reboot on decompression failure feature, due to the mentioned ugly hack not working anymore (the macro being redefined got renamed, without fixing this code).
