CVE-2023-53542

In the Linux kernel, the following vulnerability has been resolved:

ARM: dts: exynos: Use Exynos5420 compatible for the MIPI video phy

For some reason, the driver adding support for Exynos5420 MIPI phy
back in 2016 wasn't used on Exynos5420, which caused a kernel panic.
Add the proper compatible for it.
