Bootstatus mechanism is reconstructed to the latest
architecture and for all existing ASPEED BMC platforms.

Changes in v2:
  - Support SW restart on AST2600 by default without
    adding any dts property.

Changes in v3:
  - Get watchdog controller index by dividing register
    base offset by register size.

Changes in v4:
  - Update the commit message for updating bootstatus
    handling patch.
  - Rename aspeed_wdt_config struct to aspeed_wdt_data.
  - Create restart callback function.

Changes in v5:
  - Remove SW reset mechanism since there is no consensus
    about bootstatus for SW reset currently.
  - Correct the method for clearing reset event flag on
    AST2400 and AST2500 legacy platforms.

Changes in v6:
  - Use resource_size() function to get WDT controller
    registers size.

Changes in v7:
  - Update commit message. WDIOF_CARDRESET flag is
    used to represent all WDT reset events.
