phy: qcom: edp: Make the number of clocks flexible

On X Elite, the DP PHY needs another clock called ref, while all other
platforms do not.

The current X Elite devices supported upstream work fine without this
clock, because the boot firmware leaves this clock enabled. But we should
not rely on that. Also, even though this change breaks the ABI, it is
needed in order to make the driver disables this clock along with the
other ones, for a proper bring-down of the entire PHY.

So in order to handle these clocks on different platforms, make the driver
get all the clocks regardless of how many there are provided.
