ACPI: blacklist: fix clang warning for unused DMI table

[ Upstream commit b80d6a42bdc97bdb6139107d6034222e9843c6e2 ] When CONFIG_DMI is disabled, we only have a tentative declaration, which causes a warning from clang: drivers/acpi/blacklist.c:20:35: error: tentative array definition assumed to have one element [-Werror] static const struct dmi_system_id acpi_rev_dmi_table[] __initconst; As the variable is not actually used here, hide it entirely in an #ifdef to shut up the warning.
