Subject: [PATCH] ACPI: PRM: Fix missing guid_t declaration in linux/prmt.h

Seen the following build error:

 ./include/linux/prmt.h:5:27: error: unknown type name ‘guid_t’
     5 | int acpi_call_prm_handler(guid_t handler_guid, void *param_buffer);
       |                           ^~~~~~

The include file uses guid_t but it is not declared. Include
linux/uuid.h to fix this.
