exynos: usb: Switch USB VBUS GPIOs to be device tree configured
Some Exynos boards, such as the SMDK5250, control USB port power through
a GPIO pin. For now this had been hardcoded in the exynos5-dt board
file, but not all boards use the same pin, requiring local changes to
support different boards.
This patch moves the GPIO initialization into the USB host controller
drivers which they belong to, and uses the samsung,vbus-gpio parameter
in the device tree to configure it.

At present the i2c ports are enumerated in a strange way - the

is ignored and the ports are renumbered. The effect is the same provided
that the device tree has the ports in the same order, or uses aliases,
and has no gaps, but it is not correct.
Adjust the code to use the function as intended. This will allows device
tree aliases to change the device order if required.
As a result, the i2c_busses variable is dropped. We can't be sure that
there are no 'holes' in the list of buses, so must check the whole
array.
