Subject: [PATCH v1 1/1] misc/mei/hdcp: Use correct macros to initialize uuid_le

GUID_INIT() is for internal guid_t type and shouldn't be used
for the uuid_le. I.o.w. relying on the implementation details
is layering violation. Use correct macros to initialize uuid_le.

Fixes: 64e9bbdd9588 ("misc/mei/hdcp: Client driver for HDCP application")
