pc: fix wrong CMOS values for floppy drives

Before commit 63ffb564dca94f8bda01ed6d209784104630a4d2, states for

also considered whether a disk is inserted or not. The commit didn't copy

Convert linux bootrom to external rom and fw_cfg

We already have a working multiboot implementation that uses fw_cfg to get
its kernel module etc. data in int19 runtime now.

So what's missing is a working linux boot option rom. While at it I figured it
would be a good idea to take the opcode generator out of pc.c and instead use...

Convert multiboot to fw_cfg backed data storage

Right now we load the guest kernel to RAM, fire off the BIOS, hope it
doesn't clobber memory and run an option rom that jumps into the kernel.

That breaks with SeaBIOS, as that clears memory. So let's read all...

rom loader: make vga+rom loading configurable.

The rom_add_vga() and rom_add_option() macros are transformed into
functions. They look at the new rom_enable_driver_roms variable
and only do something if it is set to non-zero, making vga+option rom
loading runtime option. pc_init() sets rom_enable_driver_roms to 1....

use rom loader for pc bios.

The pc bios shows up in 'info roms' now.

Note that the BIOS is mapped to two places: The complete rom at the top
of the memory, and the first 128k at 0xe0000. Only the first place is
listed in 'info roms'.
