Clk: SPEAr1340: Update sys clock parent array
sys_clk has multiple parents and selection of parent depends on sys_clk_ctrl register bit no. 23:25, with following possibilities 0XX: pll1_clk 10X: sys_synth_clk 110: pll2_clk 111: pll3_clk Out of several possibilities (h/w wise) to select same clock parent for sys_clk, current clock implementation was considering just one value. When bootloader programmed different (valid) value to select a clock parent then Linux breaks. Here, we try to include all possibilities which can lead to same clock selection thus making Linux independent of bootloader selection values.
