Subject: [PATCH v2 2/2] ARM: dts: da850-lcdk: specify the maximum pixel clock rate for tilcdc

Due to memory throughput constraints any display mode for which the
pixel clock rate exceeds the recommended value of 37500 KHz must be
filtered out.

Specify the max-pixelclock property for the display node for
da850-lcdk.
