The atapi_eh_tur and atapi_eh_request_sense can be reused by ZPODD
code, so separate them out to a file named libata-atapi.c, and the
Makefile is modified accordingly. No functional changes should result
from this commit.

Why is this change necessary?  This doesn't seem to help anything to
me.

Function zpready introduced in patch 6 used these 2 functions to see if
an ODD is in a zero power ready state.

And why zpready can't use the functions if they're in a different file?
