msm: acpuclock-krait-debug: Add support to show the frequency table

It is useful to know what frequency table is being used on a
live target without having a debugger attached. Add support
to dump the acpu frequency table via a debugfs node.

Sample output:
/ # cat /d/acpuclk/acpu_table
CPU_KHz PLL_L_Val  L2_KHz VDD_Dig VDD_Mem BW_Mbps VDD_Core UA_Core AVS
 300000         0  300000       4 1050000     600   825000  400000   0
 422400        44  300000       4 1050000     600   825000 3200000   0
