This is a convenient way for a driver to get the hardware address of a
device, when regmap or syscon are not being used. Change existing callers
to use it as an example to others.

The dwc3_set_mode function is used only in
drivers/usb/host/xhci-exynos5.c so make it to static.

Commit 4a271cb1b4ff doesn't take into account that fdtdec_setup_gpio()
returns success when the gpio passed to it is FDT_GPIO_NONE (no
gpio node found in the fdtdec_decode_gpio() call). This results in
calling gpio_direction_output() on invalid gpio. For this reason
executing "usb start" command on Arndale causes data abort in the
ehci-exynos driver.
Add the fdt_gpio_isvalid() check to fix that problem.

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.

This adds driver layer for xHCI controller in Samsung's
exynos5 soc. This interacts with xHCI host controller stack.
