usb: phy: msm: Make phy_reset clk and reset line optional.

Browse Source 
This patch makes the phy reset clk and reset line optional as this clk
is not available on boards like IFC6410 with APQ8064.

phy-reset clk is only used as argument to the mach level callbacks, so
this patch adds condition before clk_get calls so that the driver
wouldn't fail on SOCs which do not have this support.
