ACPI: Suppress misleading SPCR console message when SPCR table is absent

Browse source

The kernel currently alway prints:
"Use ACPI SPCR as default console: No/Yes "

even on systems that lack an SPCR table. This can
mislead users into thinking the SPCR table exists
on the machines without SPCR.

With this change, the "Yes" is only printed if
the SPCR table is present, parsed and !param_acpi_nospcr.
This avoids user confusion on SPCR-less systems.
