PCI Type 2 config was a strange and never-used config mechanism.
It is unlikely that in the 13 years of coreboot's existence that
type 2 was ever used; it just made life complicated for everyone.
It lived long enough in coreboot to be replaced by mmioconf.
Prior to making the device tree visible in romstage we want to
get rid of type2.
Delete two files we don't need any more (yay!).
Replace two functions with one: pci_config_default, which returns
a pointer to the default config method. At some future time this
may change to mmio but for now it is old type1 style.

... and always include IP checksumming in romstage.
It's generally useful and our upcoming port needs it.

Since we do not run option roms in normal mode nothing was
initializing the BDA/EBDA and yet Linux depends very much
on it having sane values here. For the most part the kernel
tries to work around this not being initialized, but every
once in awhile (1/300 boots or so) it would end up reading
something that looked sane from BDA but was not and then
it would panic.
In this change the EBDA is unconditionally setup before devices
are initialized. I'm not set on the location in dev_initialize()
but there does not seem to be another place to hook it in so
that it runs just once for ALL platforms regardless of whether
they use option roms or not. (possibly hardwaremain?)
The EBDA setup code has been moved into its own location in
arch/x86/lib/ebda.c so it can be compiled in even if the option
rom code is not.
The low memory size is still set to 1MB which is enough to make
linux happy without having to hook into each mainboard to get a
more appropriate value. The setup_ebda() function takes inputs
so it could be changed for a mainboard if needed.
OLD/BROKEN would read garbage. Examples from different boots:
ebda_addr=0x75e80 lowmem=0x1553400
ebda_addr=0x5e080 lowmem=0x3e51400
ebda_addr=0x7aa80 lowmem=0x2f8a800
NEW/FIXED now reads consistent values:
ebda_addr=0xf6000 lowmem=0x100000

It's not used on any board supported by coreboot but has been
detected at run time since ages. No new boards (since 2000?)
are using the CONF2 method, so it is unlikely we ever have to
turn this on for a board.

- shift most (romcc) code out of console.h into arch/x86/lib/romcc_console.c
- rename arch/x86/lib/printk_init.c to .../romstage_console.c
- drop FUNCTIONS_FOR_PRINT since __console_tx_* are already functions, so there
should not be any side effects to eliminating another indirection.
