[LinuxBIOS] patch to cs5536 to get digital logic msm800sev working

[ron minnich]

With this patch, the msm800sev runs FILO and boots a kernel.

This is a hack. Basically, I am disabling the code which disables COM1
on thecs5536, since it is already disabled anyway. If we disable COM1
at this point, we lose all uart output. I still don't know why that
happens. I bet Marc Jones will fix it :-)

My general feeling is that we should not be messing with COM1 at this
point, it has always been a problem to enable/disable COM1 this late
in boot, if the early code has already set it up. This is a lot like
the problem the kernel faces, where the BIOS has set things up, and
the kernel needs to be told "don't touch".
