Subject: [PATCH 1/2] arm64: dts: qcom: sm8150-hdk,mtp: specify ZAP firmware
 name

The DT file has GPU node enabled, but doesn't specify the file name of
the ZAP firmware, which means using a default file name. Specify the
name to the ZAP shader firmware, pointing to the file in the
linux-firmware repo.

Fixes: f30ac26def18 ("arm64: dts: qcom: add sm8150 GPU nodes")
