[PATCH v2 -next] edac: i82975x: remove set but not used variable 'dtype'

[YueHaibing]

Fixes 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 never used since introduction in commit
084a4fccef39 ("edac: move dimm properties to struct dimm_info")

Also remove function i82975x_dram_type and move the comment and the
assignment to the single called place.
