[PATCH v5 1/3] media: verisilicon: Remove deprecated nxp,imx8mp-vpu variant

[Benjamin Gaignard <benjamin.gaignard@collabora.com>]

"nxp,imx8mq-vpu" is tagged as deprecated since:
commit f3116f2e52e6 ("media: dt-bindings: media: nxp, imx8mq-vpu: Split G1 and G2 nodes")
merged since v5.17-rc1. There is more reference to it since that.
Remove for driver to clean up the code.
