Adds back bits 57 & 56

[wmat]

Adds back bits 57 & 56 to Sscofpmf and Smcntrpmf. @gfavor and @bcstrongx , can you please make sure I added these bits back correctly?

Fixes #1578 (comment)

[gfavor]

Overall looks fine. Just one simple "typo" correction to the Smcntrpmf change - for which I created a comment. Presuming that will be fixed, I approve this set of changes.

[wmat]

So everyone is in agreement and this is good to merge now?

[bcstrongx]

I don't see any changes based on our comments? There should only be 1 file changed (sscofpmf.adoc).

@bcstrongx for smcntrpmf, there is one change:
"Bits 57:56 are reserved for possible future modes." should be replaced by "Bits 57:56 are reserved."

Ahh I see this now. I was referring to this in my earlier comment. Please ignore my previous comment if this is what going to be planned change for smcntrpmf.

@ved-rivos I removed that text a while back:
340d4b1

57:0 are all reserved in m{instret|cycle}cfg.

So only Sscofpmf has changes now, with the exception of the deletion of an extra space at the end of a line in Smcntrpmf. With approvals, this can be merged now?
