fixes the problems with PCI add-on cards not being detected or
initialized on MCP55-based systems (PCI bridge decoding change).
I have tested this on the MSI MS-7260 (K9N Neo) with a PCI VGA card,
which worked fine in any of the three PCI slots.

For example: in C51/MCP55 or C51/MCP51
Will allow
1. C51 at 0x10 to 0x14, and MCP at 0 to 4
2. C51 at 1 to 4, and MCP at 7 to 0x0a
The reason is c51/mcp51/mcp55 reported unitid is 0x0f (far beyond it
needed), and will prevent us from putting them on bus 0.
Typical values for c51/mcp55 or c51/mcp51:
HT_CHAIN_UNITID_BASE = 0x10 # for C51
HT_CHAIN_END_UNITID_BASE = 0 # for mcp
If only have mcp with c51,
HT_CHAIN_UNITID_BASE = 0 # for MCP
#HT_CHAIN_END_UNITID_BASE = 0 # default value 0x20

mostly undocumented, had a broken coding style, contained lots of dead
code and had several other problems, e.g. it enabled write access to the
ROM (why?), it unconditionally enabled primary/secondary IDE (which should
have a config option) and that even _twice_ (which is um... wrong).
The new code
- has 'ide0_enable' and 'ide1_enable' config options (which actually
work) to enable/disable the primary/secondary IDE interface in
Config.lb.
- Does _not_ enable write access to the ROM (or is there some good
reason to do that? If so, it should at least have a config option).
- Contains a bit more documentation.
- Uses readable (and documented) #defines instead of hardcoded magic values.
- aaand... it actually compiles ;-) Yep, that's right. The previous code
wouldn't even build, as it hadn't been fully ported from v1 (still used
v1 functions which are simply not available in v2).

the system boot to a command line.
This patch comments out the code to set up the vga framebuffer to allow
the system to boot, without this fix the system hangs during elfboot.
The only line that is absolutely necessary to change is the SMRAM setup,
however I've commented out all vga setup to make it very obvious to both
the kernel/payload and anyone looking at the code that vga isn't
currently working. This setup might also be better handled in
northbridge.c, if it doesn't need to be done before ram init, yet
another reason to comment it all. In the future, LinuxBIOS needs to be
told that the graphics memory area, 1mb or 512kb (at the user or
developer's option), is reserved for the onchip vga, but I'm not sure if
it's taken at the top or bottom of the memory, yet. LB may also need to
set a base address for the AGP aperture and/or be told that range is
reserved as well, whether this was originally the job of the system bios
or vga bios is still a mystery. It also corrects the number of entries
in irq_tables.c, without this fix the kernel would probably complain and
hang due to unmapped IRQs.

return that skipped the disable code. This patch removes the return and
fixes the UART disable code.
The problem was that the disable code was ORing bits into the Legacy_IO
MSR causing issues with the LPC SIOs init code that would manifest as a
hang because the IO would not be decoded correctly. ANDing to clear the
bits fixes the issue.

As per JEDEC, we should wait 200us until voltages and clocks are stable.
Then apply NOPs for 200 clock cycles (for simplicity we use 200us here).
All other delays are so low that we get away with just waiting 1us.
