Subject: [PATCH] (submit/bsd-DEV_MEM) xfree86: os-support: unexport DEV_MEM
 defines

DEV_MEM define isn't used by any drivers, and BSD seems to be the only
platform using /dev/pmem instead of /dev/mem - as well as the DEV_MEM
define from xf86_OSlib.h (Linux uses the symbol, but defines on its own)

Therefore, just define it where actually used and drop it from the global
xf86OSlib.h file.

Note that /dev/pmem refers to physical memory, not to be mixed up with
Linux's persistent memory subsys, which uses /dev/pmem[N] device nodes.
