ACPI: Set debug output flags independent of ACPICA

There was a divergence between Linux and ACPICA on the definition of ACPI_DEBUG_DEFAULT. This divergence was solved by taking ACPICA's definition in 4c1379d. After resolving the divergence, it was clear that Linux users wanted to use their old set of debug flags. This change fixes the divergence by setting these debug flags during acpi_early_init() rather than during global variable initialization in acpixf.h (owned by ACPICA).
