[media] media: davinci: vpbe: venc: move the enabling of vpss clocks to driver
The vpss clocks were enabled by calling a exported function from a driver in a machine code. calling driver code from platform code is incorrect way. This patch fixes this issue and calls the function from driver code itself.
