memtest86+: rewrite popup popdown popclear

Update the popup / popdown patch:
- Fix a copy/paste error for POP_SAVE_BUFFER_2 - it was a copy of
POP_SAVE_BUFFER_1, and needs to be updated for the new dimensions.
- SPD doesn't need any special popup/popdown now.

This is from a patch that was posted in the memtest86+ forum:

Subject: [PATCH 7/8] rewrite popup popdown popclear

merge popup and pop2up
merge popdown and pop2down
merge popclear and pop2clear

"It merge popup and pop2up, popdown and pop2down, popclear and
pop2clear. So when you change popup you don't have to change
pop2up anymore… it's less risky."
