Subject: [PATCH V2 1/9] arm64: dts: renesas: beacon kit: Configure programmable clocks
When the board was added, clock drivers were being updated done at
the same time to allow the versaclock driver to properly configure
the modes. Unfortunately, the updates were not applied to the board
files at the time they should have been, so do it now.

V2: Limit the changes to the versaclocks chips.
