[PATCH v2] phy: qcom: edp: Fix NULL pointer dereference for phy v6 (x1e80100)

[Val Packett]

For Glymur SoC support, the com_clk_fwd_cfg callback was added, and a
stub implementation was added for the v4 of the hardware. However it
was omitted for the v6, causing a NULL pointer dereference oops on
Hamoa/Purwa (X1E/X1P) SoC devices. Fix by adding the appropriate stub.
