Subject: [PATCH 02/13] arm64: dts: imx8mp: re-parent
 IMX8MP_CLK_MEDIA_MIPI_PHY1_REF

From: Benjamin Bara <benjamin.bara@...data.com>

Similar to commit 07bb2e368820 ("arm64: dts: imx8mp: Fix video clock
parents") the parent of IMX8MP_CLK_MEDIA_MIPI_PHY1_REF should be set in
the media_blk_ctrl. Currently, if mipi_dsi is not in use, its parent is
set to IMX8MP_VIDEO_PLL1_OUT, and might therefore clash with the
constraints coming from a panel.
