x86, acpi, tboot: Have a ACPI os prepare sleep instead of calling tboot_sleep.
The ACPI suspend path makes a call to tboot_sleep right before it writes the PM1A, PM1B values. We replace the direct call to tboot via an registration callback similar to __acpi_register_gsi.

Wysocki <rjw@sisk.pl> [v1: Added __attribute__ ((unused))] [v2: Introduced a wrapper instead of changing tboot_sleep return values] [v3: Added return value AE_CTRL_SKIP for acpi_os_sleep_prepare] Signed-off-by: Tang Liang <liang.tang@oracle.com> [v1: Fix compile issues on IA64 and PPC64] [v2: Fix where __acpi_os_prepare_sleep==NULL and did not go in sleep properly] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
