Add reg-names and interrupts for LLCC documentation and the usage

which is used for llcc broadcast writes.
Typo in the subject.
This binding just landed recently and it's already being updated? Sigh.
Bindings should be complete from the start. Technically, you can't add
new required properties.
Sure, I'll correct the typo.
llcc broadcast base was being computed from the number of banks which
was incorrect,
so we have to add this property.
And the interrupt is needed for EDAC functionality.
