aspeed/wdt: Fix ast2500/ast2600 default reload value 

Per ast2500_2520_datasheet_v1.8 and ast2600v11.pdf, the default value of
WDT00 and WDT04 is 0x014FB180 for ast2500/ast2600.
Add default_status and default_reload_value attributes for storing
counter status and reload value as they are different from ast2400.
