drm: verisilicon: suppress snprintf warning for pixel clock name
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.
