Although it's generally expected that the pixel clock ID will only have one decimal digit, this isn't enforced in vs_dc.c source code, and the compiler will argue about the buffer being not long enough.
Enlarge the snprintf() buffer for generating pixel clock name to be enough for a UINT_MAX pixel clock ID in order to suppress the compiler warning.
