The 800MHz opp speed grading fuse mask should be 0xd instead
of 0xf according to fuse map definition:
SPEED_GRADING[1:0] MHz
00 800
01 500
10 1000
11 1200

Add "opp-suspend" property for i.MX7D to make sure system
suspend with max available opp.

Are you going to add the 500mhz OPP as well?

So far no, as datasheet does NOT list 500MHz as OPP, this patch is just to make sure
the speed grading mask settings matches the fusemap file, NOT sure if 500MHz will be supported
officially.
