Please don't use

gArmTokenSpaceGuid.PcdGenericWatchdogXXXBase

to describe two different instances of the IP that are %!@ MB apart.

Instead, you could introduce your own PCDs in the HiSilicon token
space, but I am also fine with creating local #defines in this file if
the watchdog is not used anywhere else.

I don't know what happened there :-) That should be 512 MB, obviously.

Yes they are not used anywhere else, and the number of SBSA watchdogs is SoC
related, so I will use local #defines. And I think we can simply change the
content of the macros when things change in the future.
