msm8974: add HTC One M8 (htc-m8)

Support the HTC One (M8) devices. Like for the htc-memul, the htc,project-id from the vendor device tree (and used by the bootloader) is used as the qcom,msm-id. Then, the match is done on the panel compatible, which is also extracted from the vendor device tree. Signed-off-by: Alexandre Messier <alex@me.ssier.org>
