The vboot_handoff structure needs to be parsed from the coreboot tables.
Add a placeholder in sysinfo as well as the ability to parse the
coreboot table entry concering the vboot_handoff structure.
Built with unified boot loader and ebuild changes. Can find and use
the VbInitParams for doing kernel selection.

The timekeeping code in libpayload was dependent on rdtsc, and when it was
split up by arch, that code was duplicated even though it was mostly the same.
This change factors out actually reading the count from the timer and the
speed of the timer and puts the definitions of ndelay, udelay, mdelay and
delay into generic code. Then, in x86, the timer_hz and timer_get_raw_value
functions which used to be in depthcharge were moved over to libpayload's
arch/x86/timer.c. In ARM where there isn't a single, canonical timer, those
functions are omitted with the intention that they'll be implemented by a
specific timer driver chosen elsewhere.

Default it to no to be consistent with the other architecture wide options
(endianness), and turn it on explicitly for x86 and PowerPC.

The interval used to be about 55 ms which is excessively long. Coreboot only
waits for 2 ms and gets a reasonable answer. That should be good enough for us
as well.

Since it's utterly architecture-dependent, put it in arch/x86.
Avoid the temptation to make yet another directory with just one
file in it. Fix the makefile to pick up the proper arch-dependent script.

Upgrade CBFS in libpayload to use new media-based implementation from coreboot
( http://review.coreboot.org/#/c/2182/ ).
Old CBFS functions (cbfs_find, cbfs_find_file, get_cbfs_header) are still
supported, although the recommended way is to use new CBFS API.
To migrate your existing x86 payload source:
- Change cbfs_find to cbfs_get_file
- Change cbfs_find_file to cbfs_get_file_content
- Prefix every CBFS call with a CBFS_DEFAULT_MEDIA argument.
Ex, char *jpeg_data = cbfs_find_file("splash.jpg", CBFS_TYPE_BOOTSPLASH);
=> char *jpeg_data = cbfs_get_file_content(
CBFS_DEFAULT_MEDIA, "splash.jpg", CBFS_TYPE_BOOTSPLASH);
The legacy setup_cbfs_from_{ram,flash} is also supported, although the better
equivalent is to make a new media instance:
struct cbfs_media ram_media;
init_cbfs_ram_media(&ram_media, start, size);
char *data = cbfs_get_file_content(&ram_media, "myfile", my_type);
Verified by being successfully linked with filo.
