Randy Li e0a1d6579d [drm]: use mmap() in native way for GNU Linux target
The "[drm]: fix runtime error for 32bit library" is hack way,
it won't work at GNU Linux platform. Also you need to check
_FILE_OFFSET_BITS and _LARGEFILE64_SOURCE before use the
mmap64().

For the normal mmap() with glibc, we only request to
check offset is aligned with page size but not the lenght.
But that doesn't apply for the memory from the drm device,
also the android use a different rule.

I decide not to map all the buffer to cpu at beginning
since most of them won't be access by the cpu.
