LF-4682: arm: dts: imx6qdl_sabresd: remove reg_hdmi power supply
pmic_5V default is always on when imx6 Sabresd board bootup.
HDMI require the 5V keep in power ON for detect cable status,
and pmic_5v will not be off after HDMI driver probe.
On 5.15 branch, more strict device links check suppliers applied.
reg_hdmi regulator will be put into defer probe list because of i2c2,
and so will hdmi video driver.
It break ipu fb and mxc hdmi bootup sequency,
ipu fb and hdmi driver couldn't support this case and hdmi will fail to work.
Comment out reg_hdmi regulator from hdmi_video property to workaround the
issue.
