Subject: [PATCH 5.19 0460/1157] media: mediatek: vcodec: decoder: Skip alignment for default resolution

From: Chen-Yu Tsai <wenst@...omium.org>

[ Upstream commit 3b6a81a31370539f1fd0e9bdd315503aa154285e ]

The default resolution of 64x64 is already aligned, according to the
call to v4l_bound_align_image() in mtk_vcodec_dec_set_default_params().

Drop the redundant v4l_bound_align_image() call. This also removes one
usage of ctx->max_{width,height}.
