Subject: [PATCH v2] Staging: dt3155: make local variables static

The symbols dt3155_dev_open, unique_tag, and allocatorAddr are only used in
the file dt3155_drv.c and should be static. Also, as pointed out by Joe Perches,
static variables do not need initialization so remove them. While here, also
move the definition for allocatorAddr so that all the variables are declared at
one place in the code.
