ENGR00137983 MX53: Update CPU working points

- Set working points for different part numbers according
to RevD datasheet.
- Put MX53 working point settings in new files.
- For Auto, only 800MHZ working point is added. Since the SW uses
PLL1 to judge chip part number now, the chip will be treated as
auto chip if the user set PLL1 as 800MHZ in U-Boot. If there is a
better way to get part number information, we will revise part
number setting codes in clock.c.
- The voltages for 160MHZ is "TBD" in datasheet. Set it as
0.9V firstly.
- To run 1.2GHZ CPU, do as the following in U-Boot:
i2c mw 0x48 0x2e 0x60
clk core 1200
Before executing the command, you must ensure your chip is
1.2GHZ chip
