I just found another caveat: while `select' is some super-override-it-all that
ignores depends on non-existent symbols, it doesn't promote `m' to `y'.
E.g. `select FB_CFB_FILLRECT' from a bool still gives FB_CFB_FILLRECT=m if
FB=m.

Anyway, here's a fix for the 3 problematic cases I found.

Subject: bool fbdevs must depend on FB = y

Frame buffer device drivers that cannot be built as modules must depend on
`FB = y'.  Correct the 3 remaining offenders.
