watchdog: sbsa: only use 32-bit accessors
SBSA says of the generic watchdog: All registers are 32 bits in size and should be accessed using 32-bit reads and writes. If an access size other than 32 bits is used then the results are IMPLEMENTATION DEFINED. and for qemu, the implementation will only allow 32-bit accesses resulting in a synchronous external abort when configuring the watchdog. Use lo_hi_* accessors rather than a readq/writeq.
