IntelFrameworkModulePkg/LegacyBios: Fix legacy serial redirection bug
Upon booting to a legacy OS, LegacyBios driver is responsible to
initialize the BDA region with the correct COM port base address.
But the current logic to get the COM port base address from IsaIo
instance is not correct.
The patch fixes this bug.
