Subject: Add basic support for FDT to i386 & amd64. This change includes: 1. 
 Common headers for fdt.h and ofw_machdep.h under x86/include     with
 indirections under i386/include and amd64/include. 2.  New modinfo for loader
 provided FDT blob. 3.  Common x86_init_fdt() called from hammer_time() on
 amd64 and     init386() on i386. 4.  Split-off FDT specific low-level console
 functions from FDT     bus methods for the uart(4) driver. The low-level
 console     logic has been moved to uart_cpu_fdt.c and is used for arm,    
 mips & powerpc only. The FDT bus methods are shared across     all
 architectures. 5.  Add dev/fdt/fdt_x86.c to hold the fdt_fixup_table[] and
 the     fdt_pic_table[] arrays. Both are empty right now.

FDT addresses are I/O ports on x86. Since the core FDT code does
not handle different address spaces, adding support for both I/O
ports and memory addresses requires some thought and discussion.
It may be better to use a compile-time option that controls this.
