ACPI: run _OSC after ACPI_FULL_INITIALIZATION
commit fc54ab72959edbf229b65ac74b2f122d799ca002 upstream.
The _OSC method may exist in module level code,
so it must be called after ACPI_FULL_INITIALIZATION
On some new platforms with Zero-Power-Optical-Disk-Drive (ZPODD)
support, this fix is necessary to save power.
