Pedro F. Giffuni a0dedc3034 Clean redundant MIN/MAX declarations in some HighPoint drivers. 
The hpt27xx(4), hptnr(4), and hptrr(4) drivers declare MIN() and MAX()
internally which match the macros from sys/param.h.

MIN() is not used, MAX is only used once and can be replaced with the
max() version in libkern.h which operates on u_ints.
