platform/x86: wmi: Add wmidev_block_set()
Currently, WMI drivers have to use the deprecated GUID-based
interface when setting data blocks. This prevents those
drivers from fully moving away from this interface.
Provide wmidev_block_set() so drivers using wmi_set_block() can
fully migrate to the modern bus-based interface.
Tested with a custom SSDT from the Intel Slim Bootloader project.
