kernel: change kernel version from 3.4 to 3.8

No other change was done apart from switching 3.4 to 3.8. It seems that
the configuration variables work as expected. It will need testing.
logo.cfg, alix3d3.cfg: add logo, change framebuffer option in kernel
alix3d3.conf: add debugshell=5 parameter to wait for 5 seconds to debug
linux-yotco: alix3d3.cfg: add ALIX related configuration variables

Add bunch of ALIX related configuration to get the machine booted.
Including are CS5536 PATA, CRYPTO, PCMCIA configs, CF Card support,
CS5535 sound, etc.

We need to split them up when we are sure that the kernel configuration
works. Currently, one config file is used to easily test/debug the
configuration.
TODO: update
README.md: update the branch information. Switch to dylan
linux-yocto: enable VIA RHINE ethernet and DEVTMPFS configs
linux-yocto: split the configuration variables into fragments
linux-yocto: enable cs5535 gpio, mfd and serial support
alix3d3.cfg: remove commented line for 3.4 kernel.

Kernel version 3.8 works with the board and 3.4 release was older. It
was tested when this BSP work started.
alix3d3.conf: Disable SERIAL and enable explicit configuration

At first ia32-base.conf was extended. However, this configuration is
generic for all intel architecture and it did not fit out needs.
ia32-base set SERIAL_CONSOLE which we do not want getty to bind. The
board has VGA that are used for console. The serial port will be used
for other purposes.

Move XSERVER option from base configuration as wel.
