ntb_hw(4): Allow any x86 PAT caching flags for MW defaults

Replace the hw.ntb.enable_writecombine tunable with
hw.ntb.default_mw_pat.  It can be set with several specific numerical
values to select a caching type.  Any bogus value is treated as
Uncacheable (UC).

The ntb_mw_set_wc() KPI has removed the restriction that the selected
mode must be one of UC, WC, or WB.
