There was a divergence between Linux and ACPICA on the definition of
ACPI_DEBUG_DEFAULT. This divergence was solved by taking ACPICA's
definition. 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).

Fixes: 4c1379d7bb42 (ACPICA: Debug output: Add option to display method/object evaluation)
