This patch adds a loader-target.c file for target-specific
rom loading functions.  The rom_add_vga() and rom_add_option()
macros are transformed into functions and sticked in there.  They
load the bios on TARGET_I386 and no nothing on other targets.

With this in place we can move the rom loading calls from pc.c to the
individual drivers.
