This change de-asserts vbus_gpio on suspend and
re-asserts on resume in order to save power.
NOTE, this change means no USB charging in suspend
mode.

By enabling runtime pm in this driver allows users of
xhci-plat to enter into runtime pm. This is not full
runtime pm support (AKA xhci-plat doesn't actually power
anything off when in runtime suspend mode) but,
just basic enablement.

Exynos5250 has external PLL (XusbXTI) for USB 3.0 PHY's
ref_pad_clk. So use this clock based on availability of
gpio to power control this PLL, otherwise use internal
clock only from XXTI.
