bugzilla: NA
CVE: NA

-------------------------------------------------

The commit 4daf80d7164 ("arm64/ascend: Enable...") missed to set the
correct dvpp mmap area when the user didn't set the MAP_DVPP flags,
so add new area zone to fix this.

And fix some coding style, rename the enable_map_dvpp to
enable_mmap_dvpp.

v2: return true if the input addr is DVPP_MMAP_BASE for dvpp_mmap_zone.

Fixes: 4daf80d7164 ("arm64/ascend: Enable DvPP mmap features for Ascend Platform")
