Subject: [PATCH v2 00/10] ufs-qcom: phy/hcd: Clean up qcom-ufs phy and ufs-qcom hcd

These patches cleanup the ufs phy driver to an extent.
Subsequent patches will target to clean the phy_init() of
these qcom-ufs phy drivers in order to get rid of a number of
exported APIs that phy drivers expose for ufs-qcom hcd driver
to use.

These patches are based on linux-phy next branch, and have been
tested with on db820c hardware with integration branch -
'integration-linux-qcomlt' of qualcomm linaro lt tree [1].

Changes from v1:
 1) Added a patch to the series to remove following unnecessary
    function declarations by moving the code:
    - __ufs_qcom_phy_init_vreg(),
    - ufs_qcom_phy_init_vreg(),
    - ufs_qcom_phy_base_init()
 2) Cleaned up following functions further for patch [2]:
    - ufs_qcom_phy_enable(/disable)_ref_clk()
    - ufs_qcom_phy_enable(/disable)_iface_clk()
 3) Added patch to add phy_exit() call to ufs-qcom exit path.
 4) Added a patch to remove ufs_qcom_phy_exit() from 'phy-qcom-ufs'
    driver, since this api just powers off the phy.
