Make DGA, CPIO, non-PCI, and TV-Out support detected per-platform, using

    the same semantics as in drivers/ati/Imakefile.

+# Note that this is sort of inverted from drivers/ati/Imakefile in
+# the monolith.  We test for foo, not for !foo (i.e. ATMISC_CPIO, not
+# ATIMISC_AVOID_CPIO), but the defines are negative.  So beware.  Oh yeah,
+# TV_OUT is the special case where it's a positive define, not AVOID_TV_OUT.
+
+# AVOID_CPIO: Only x86, amd64, and alpha are cool with CPIO.  It needs a
+# little-endian, undirected PIO space of at least 64kB.
+# AVOID_NON_PCI: Platforms which don't deal with PCI master aborts should
+# stick to PCI-only probing, stick their fingers in their ears, and pretend
+# that ISA cards simply don't exist.
+# AVOID_DGA: ???
+# ATI_TV_OUT: This only works on x86.
