Changes from v7:
 - Rebased on 'xceive' of Balbi's usb tree.
 - Placing proper Acked By's received for each patch.

Changes from v6:
 - Changing macro names from 'HOST_CTRL0_FSEL_CLKSEL_XX' to 'FSEL_CLKSEL_XX'
   since it's being used by HOST and OTG block to prepare reference clock.
 - Directly Assigning 'FSEL_CLKSEL_XX' to refclk_freq in
   samsung_usbphy_get_refclk_freq() instead of ORing them since we are
   anyways using macros:
        "HOST_CTRL0_FSEL(_x)                    ((_x) << 16)"
        "OTG_SYS_FSEL(_x)                       ((_x) << 4)"

Changes from v5:
 - Adding hostphy enable mask and hostphy register offsets
   to driver data in order to access the HOSTPHY CONTROL register.

 - Adding member 'otg' to struct samsung-usbphy so that its consumers
   can call otg->set_host so as to make 'phy' aware of the consumer type:
        HOST/DEVICE

 - Adding 'otg' to 'struct s5p_ehci_hcd' and 'struct exynos_ohci_hcd'
   which keeps track of 'otg' of the controllers' phy. This then sets
   the host.

 - Moved samsung_usbphy_set_type() calls from ehci-s5p and ohci-exynos
   to phy driver itself where based on phy_type it is called.

 - Added separate macro definition for USB20PHY_CFG register to select
   between host/device type usb link.

 - Removing unnecessary argument 'phy_type' from samsung_usbphy_set_type()
   and samsung_usbphy_cfg_sel().

 - Addressed few nits:
        -- added macro for 'KHZ'
        -- removing useless 'if' from samsung_usbphy_cfg_sel()
        -- keeping the place of clk_get intact and requesting driver
           data before that.
