This SoC already provides a system controller node to access reset status register needed for the watchdog. Instead of using MIPS architecture dependent operations in header 'asm/mach-ralink/ralink_regs.h' use a phandle to the system controller node and use it through regmap APIs from the code. Driver is also using some globals that are not needed at all if a driver data structure is used along the code. Hence, add all new needed stuff inside a new driver data structure. With this changes driver can be properly compile tested. Thanks in advance for reviewing this!
