*_minphys() functions that cap i/o sizes at a value larger than the
value minphys() uses (MAXPHYS) are pointless since minphys() is always
called after the *_minphys() function.
MAXPHYS (64 * 1024) == 16 * 4096. 4096 is the smallest PAGE_SIZE we
have. So a *_minphys() function that caps the i/o size at N *
PAGE_SIZE where N is > 16 is just wasting cycles.
