ARM: defconfig: u8500: Enable new drivers for ux500

The new device tree for samsung-skomer and the HREF520
devicetree enables some additional drivers that are not yet
selected in the u8500_defconfig:

- The GPIO-based I2C bus master driver for some peripherals
  that do not use the I2C hardware master.
- The Novatek NT35510 driver for the Skomer panel.
- The Sony ACX424AKP driver for the HREF520 panel.
- The GPIO-based backlight driver for Skomer.
- The BMA180 driver for the BMA254 accelerometer found in the
  Skomer.
- The new GP2AP002 driver for the GP2AP002S00F proximimty sensor
  found in the Skomer and Golden devices.
