[LinuxBIOS] patch: digital logic msm800 sev support

[ron minnich]

This modifies the latest tree for digital logic msm 800 sev.
Unfortunately, it is locking up at post code 88, with this:
Initializing devices...
Root Device init
MSM800SEV ENTER init
MSM800SEV EXIT init
PCI: 00:01.0 init
>> Entering northbridge.c: northbridge_init
PCI: 00:01.1 init
PCI: 00:0f.0 init
cs5536: southbridge_init
RTC Init
GPIO_ADDR: 00001000


This is not the behaviour seen on the private tree I got from AMD, and
patched, so I need to figure out what is up.

This patch includes:
changes to mainboard/digitallogic/msm800sev, targets/digitallogic/msm800sev
It includes one label added to the lx cache_as_ram.inc, because once
ram is turned on, the return from function cache_as_main in
mainboard/digitallogic/msm800sev/cache_as_ram_auto.c fails. Please see
the patch for details.

This is not quite there, but I wanted to start getting the changes in.
It builds, but does not work completely.
