From: "Lad, Prabhakar" <prabhakar.csengg@xxxxxxxxx>
This patch fixes the DT binding properties of adv7343 decoder.
The pdata which was being read from the DT property, is removed
as this can done internally in the driver using cable detection
register.
This patch also removes the pdata of ADV7343 which was passed from
DA850 machine.

Required Properties :

+- vddcore-supply: core voltage supply.
+- vaa-supply: Analog power supply.

Optional Properties :
-- adi,power-mode-sleep-mode: on enable the current consumption is reduced to
- micro ampere level. All DACs and the internal PLL
- circuit are disabled.
-- adi,power-mode-pll-ctrl: PLL and oversampling control. This control allows
