- actually hook up usbdebug in printk/print_ for romstage
- make usbdebug.c more similar to the Linux kernel version it was
originally derived from.
- increase retries and timing for usbdebug init (at least one chipset
seems to need this)
- src/pc80/usbdebug_serial.c is not needed
- some small console cleanups

coreboot made it kind of complicated to print a character on serial. Not quite
as complicated as UEFI, but too much for a good design. Fix it.

initializing VGA happens pretty much as the last thing before starting the
payload. Hence, drop VGA console support, as we did in coreboot v3.
- Drop VGA and BTEXT console support.
Console is meant to be debugging only, and by the time graphics comes up
99% of the risky stuff has already happened. Note: This patch does not remove
hardware init but only the actual output functionality.
The ragexl driver needs some extra love, but that's for another day
- factor out die() and post()
- drop some leftover RAMBASE < 0x100000 checks.

makes include/console/console.h and console/console.c usable both in
__PRE_RAM__ and coreboot_ram stages.
While debugging this, I removed an indirection from the e7520 ram init code
(same as we did on a couple of other chipsets, removes some register pressure
from romcc)
Also, drop remainders of CONFIG_USE_INIT (except the one odd piece of dead code
in cache_as_ram.inc)
Then some ap_romstage.c fixes, at least the nvidia/l1_2pvv compiled for me with
CONFIG_AP_CODE_IN_CAR set in Kconfig which it did not before.

Interesting enough, console_printk was only used in a single place and
duplicated a large part of console.h which is included in the same place.
Thus, just drop console_printk.c and we're one down with console complexity

Stepan pointed out that "s" means string, which makes the following statement
in this commit message invalid: "Since we either have reserved space (which
we shouldn't do anything with in these two functions), an enum or a
hexadecimal value, unsigned int seemed like the way to go."

To ease some of my debugging pain on the unichrome, i decided i needed to
move FB size selection into cmos, so i could test a size and then reset it
to the default after loading this value so that the next reboot uses the
(working) default again. This meant implementing set_option in parallel to
get_option.
get_option was then found to have inversed argument ordering (like outb) and
passing char * and then depending on the cmos layout length, which made me
feel quite uncomfortable. Since we either have reserved space (which we
shouldn't do anything with in these two functions), an enum or a
hexadecimal value, unsigned int seemed like the way to go. So all users of
get_option now have their arguments inversed and switched from using ints
to unsigned ints now.
The way get_cmos_value was implemented forced us to not overlap byte and to
have multibyte values be byte aligned. This logic is now adapted to do a
full uint32_t read (when needed) at any offset and any length up to 32, and
the shifting all happens inside an uint32_t as well. set_cmos_value was
implemented similarly. Both routines have been extensively tested in a
quick separate little program as it is not easy to get this stuff right.
build_opt_tbl.c was altered to function correctly within these new
parameters. The enum value retrieval has been changed strol(..., NULL, 10)
to stroul(..., NULL, 0), so that we not only are able to use unsigned ints
now but so that we also interprete hex values correctly. The 32bit limit
gets imposed on all entries not marked reserved, an unused "user_data" field
that appeared in a lot of cmos.layouts has been changed to reserved as well.

This code brings a rather complete set of VGA IO routines for whoever wants it.
These consist of the by now familiar read/write/mask sets. Due to the crazy
nature of VGA, an ancient standard with bits all over the place, it makes no
sense to define individual registers. You need a vga register spec at hand if
you want to do anything anyway. These IO routines are always exposed.
It also provides code to natively set up a 640x400 VGA textmode with an 8x16
font. The native VGA mode code is behind the OPTION_VGA option, as the font
really adds to the size of the compiled/compressed rom. The font is the one
also present in the linux kernel, but this file is unlicensed. Another copy of
this is also present in coreboot in the deprecated console/btext code.
The vga console code has been cleaned up, but it still has some TODO's left
open, but that's for when i finally have found the remaining issue with the
epia-m. Right now, it is important to get parts of my work out already and to
make the remainder managable again.

this type of checking in the v3 code since ages, but v2 will happily
compile any code with bogus printk format strings and/or parameters.
This can cause real bugs and at least needs to emit a warning, if not
an
error. Go with a warning for now since most of the flagged format
strings are wrong but harmless in a 32-bit x86 environment.
