acpi_evaluate_dsm() and friends take a pointer to a raw buffer of 16
bytes. Instead we convert them to use uuid_le type. At the same time
we
convert current users.

acpi_str_to_uuid() becomes useless after the conversion and it's safe
to
get rid of it.

The conversion fixes a potential bug in int340x_thermal as well since
we have to use memcmp() on binary data.
