Changes from v4:
- Moved architecture side changes out of this patch-set.
- Added support for multiple usbphy phandle parsing and
doing all pmu_isolation() and phy_cfg_sel() related changes
in samsung-usbphy driver only instead of architecture
as in v4 patch-set.
- Removed unnecessary multi line definitions for macros.
Changes from v3:
- Moved enums S5P_USB_PHY_DEVICE, S5P_USB_PHY_HOST from machine to file
include/linux/usb/samsung_usb_phy.h as USB_PHY_TYPE_DEVICE and
USB_PHY_TYPE_HOST to make it more generic. Further resolve its
dependencies.
- Introduced a function 'samsung_usbphy_set_type()' which takes
care of setting up the phy_type: HOST/DEVICE. This function
can be called by host/otg drivers to setup phy_type prior to
handling the respective PHYs.
- Added an error-path for HOST type phy in s5p_usb_phy_pmu_isolation()
for 'mach-s3c64xx'.
- Moving to PHY driver as default for ehci-s5p and ohci-exynos, and only
when failed fall back to plat-data.
- Added samsung_usbphy_set_type() prior to doing usb_phy_init() or
usb_phy_shutdown() so that appropriate PHY gets init or shutdown.
