stable inclusion from stable-v5.10.110 commit ef1df9168532cf00e65ccee43c0fe95f78f84d21 bugzilla: https://gitee.com/openeuler/kernel/issues/I574AL
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
--------------------------------
commit 453a24ded415f7fce0499c6b0a2c7b28f84911f2 upstream.
Add required VDD supplies to HDMI block on SMDK5420. Without them, the HDMI driver won't probe. Because of lack of schematics, use same supplies as on Arndale Octa and Odroid XU3 boards (voltage matches).
