Subject: [Patch v3 2/3] ARM: dts: am437x-sk-evm: Add VPFE and OV2659 entries

Add VPFE device nodes entries.
Add OmniVision OV2659 sensor device nodes and linkage.

The sensor clock (xvclk) is sourced from clkout1.
Add clock entries to properly select clkout1 and set its parent
clock to sys_clkin_ck.
