clk:spear1310:Fix: Rename clk ids within predefined limit

The max limit of con_id is 16 and dev_id is 20. As of now for spear1310, many
clk ids are exceeding this predefined limit.

This patch is intended to rename clk ids like:
    mux_clk -> _mclk
    gate_clk -> _gclk
    synth_clk -> syn_clk
    gmac_phy -> phy_
    gmii_125m_pad -> gmii_pad
