Add DDC & EDID support and use it to automatically select the native mode of
the attached monitor. This can be disabled by adding edid=0 as option
to the video-mode env. variable.

Add support for the standard video-mode environment variable using the
videomodes.c video_get_ctfb_res_modes() helper function.
This will allow users to specify the resolution e.g. :
setenv video-mode sunxi:video-mode=1280x1024-24@60
saveenv
Also make the reserved fb mem slightly larger to allow 1920x1200 to work.

The CONFIG_UART0_PORT_F option has been supported since
http://git.denx.de/?p=u-boot.git;a=commit;h=ff2b47f6a9cc1025
This option is primarily useful only for low level u-boot debugging
on tablets, where normal UART0 is difficult to access and requires
device disassembly and/or soldering.
This patch now allows it to be selected from menuconfig. A dependency on
SPL_FEL is added because u-boot does not support booting from NAND yet
and also booting from SD card is impossible when a MicroSD breakout board
is plugged into the SD slot.
Additionally a compilation problem is fixed:
common/spl/built-in.o: In function `spl_mmc_load_image':
/tmp/u-boot-sunxi/common/spl/spl_mmc.c:94: undefined reference to `mmc_initialize'
/tmp/u-boot-sunxi/common/spl/spl_mmc.c:96: undefined reference to `find_mmc_device'

Change SYS_CONFIG_NAME and DEFAULT_DEVICE_TREE to chromebook_link
which is currently the only real board officially supported to run
U-Boot loaded by coreboot.
Note the symbolic link file chromebook_link.dts is deleted and
link.dts is renamed to chromebook_link.dts.
To avoid multiple definition of video_hw_init, the CONFIG_VIDEO_X86
define needs to be moved to arch/x86/cpu/ivybridge/Kconfig.

- fdtdec_get_pci_vendev() for vendor id and device id
- fdtdec_get_pci_bdf() for pci device bdf triplet
- fdtdec_get_pci_bar32() for pci device register bar

(Include <pci.h> in fdtdec.h and adjust tegra to fix build error)
Introduce a gd->hose to save the pci hose in the early phase so that
apis in drivers/pci/pci.c can be used before relocation. Architecture
codes need assign a valid gd->hose in the early phase.
Some variables are declared as static so change them to be either
stack variable or global data member so that they can be used before
relocation, except the 'indent' used by CONFIG_PCI_SCAN_SHOW which
just affects some print format.

When CONFIG_TRACE is disabled, linking fails with:
common/built-in.o:(.data.init_sequence_f+0x8): undefined reference to `trace_early_init'
To fix, wrap trace init calls with #ifdef CONFIG_TRACE.
While at it, remove the static inline version of the init call from
trace.h as suggested by Simon Glass, since it doesnt work.
