[U-Boot] [U-Boot PATCH 0/3] Add support for pcf8575

[Vignesh R]

Hi,

This adds driver for pcf8575 in uboot. The driver supports basic
read and write operations on pcf gpio pins.

The first patch adds the driver, second patch and third patch
switches cpsw to use slave0 on DRA72 EVM.

Tested pcf driver on DRA72 EVM by probing pcf lines and cpsw by 
runnning tftp.

  ARM: dra7xx_evm: Enable pcf driver
