[PATCH] xen: acpi: Hide UART address only if SPCR exists

[Masami Hiramatsu <masami.hiramatsu@xxxxxxxxxx>]

Hi,

With Julien's ACPI fix, I found my DeveloperBox (
https://www.96boards.org/product/developerbox/ ) still failed
to boot bcause of SPCR issue. According to the UEFI EDK2
implementation, the SCPR table will not be made if user
chooses graphical console instead of serial.
In such case, we should ignore the SPCR missing error.

Compared with Linux kernel implementation, this doesn't check
the STAO (status override) table, becaue it seems STAO (or XENV)
will be provided by Xen itself.
Or, should we check STAO too?

Thank you,
