From: Lad, Prabhakar <prabhakar.csengg@gmail.com>

the ths7303_setup() was doing the same thing as ths7303_setval()
except that ths7303_setval() sets it to some particular mode.
This patch removes ths7303_setup() function and calls ths7303_setval()
in the probe setting the device to 480I_576I filter mode in the probe.
