Watchdog: move get and set watchdog to new api.

Rewrite "get and set watchdog" command to use the newly
introduced ipmi api.

Tested:
Verified using ipmitool "get and set watchdog",
timer behavior is same before and after the changes.

Testing Procedure:
default watchdog timer is 11.2 seconds.

ipmitool raw 0x06 0x25      ---> Get
Output: 00 00 00 00 70 17 70 17

Note: Here 70 count(hex value)->112 count(decimal value)->112*100=11200ms
[100ms per count]->11.2sec (watchdog timer)

watchdog timer set to 20 seconds.

ipmitool raw 0x06 0x24 0x44 0x01 0x00 0x10 0xc8 0x00   ----> Set
output:

ipmitool raw 0x06 0x25    ---> Get
output: 04 01 00 00 c8 00 c8 00

Note: Here 20sec->20000ms->200count->c8 (hex value)
