[LinuxBIOS] [Patch] AMD cs5536 uart disable

[Marc Jones]

The UART disable code was causing a hang and was worked around with a 
return that skipped the disable code. This patch removes the return and 
fixes the UART disable code.

The problem was that the disable code was ORing bits into the Legacy_IO 
MSR causing issues with the LPC SIOs init code that would manifest as a 
hang because the IO would not be decoded correctly. ANDing to clear the 
bits fixes the issue.
