EDAC, i82975x: Remove set but not used variable dtype
Fix this gcc -Wunused-but-set-variable warning:
drivers/edac/i82975x_edac.c:378:16: warning: variable 'dtype'
set but not used [-Wunused-but-set-variable]
It was introduced in
084a4fccef39 ("edac: move dimm properties to struct dimm_info")
but never used.
Also, remove the function i82975x_dram_type() and move the comment and
the assignment to the place where it is used.
[ bp: massage commit message and shorten comment. ]
