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.
