[PATCH 2/3] phy: qcom: edp: Add missing refclk for X1E80100

[Abel Vesa <abel.vesa@linaro.org>]

On X Elite, the DP PHY needs another clock called refclk.
Rework the match data to allow passing different number of clocks and
add the refclk to the X1E80100 config data.

Cc: stable@vger.kernel.org # v6.10
Fixes: db83c107dc29 ("phy: qcom: edp: Add v6 specific ops and X1E80100 platform support")
