davinci_set_pllrate - set the output rate of a given PLL.
Note: Currently tested to work with OMAP-L138 only.
: pll whose rate needs to be changed. : The pre divider value. Passing 0 disables the pre-divider. : The multiplier value. Passing 0 leads to multiply-by-one. : The post divider value. Passing 0 disables the post-divider.

davinci_set_refclk_rate() - Set the reference clock rate : The new rate.
Sets the reference clock rate to a given value. This will most likely result in the entire clock tree getting updated.
This is used to support boards which use a reference clock different than that used by default in <soc>.c file. The reference clock rate should be updated early in the boot process; ideally soon after the clock tree has been initialized once with the default reference clock rate (davinci_common_init()).
Returns 0 on success, error otherwise.
