driver/anx7447: Modify Vconn SW protection time of inrush current and power SW short protect current.
The default values of Vconn SW protection time of inrush current is 19us and power SW short protect current is 370mA, it finds that the current of Vconn will up to 656mA during press F3+power button with Huawei dongle plugged in MB, then Vconn will drop when the large current happen. Vendor suggest to adjust Vconn SW protection time of inrush current(modify register 0xAA from 19us to 2.43ms) and power SW short protect current(modify register 0xA8 from 370mA to 440mA). BUG=b:119540455 BRANCH=none TEST=The HDMI display well with Huawei dongle at MB side when pressing F3+ power button to reboot OS.
