a61dc139ce staging: sm750fb: simplify PLL divisors calculations
The calcPllValues currently uses arrays of PLL parametres that contain
possible PLL control register field values and redundant data that is
calculated according to those values. The usage of these arrays can be
replaced with simple arithmetics.

7751e0e2d2 staging: sm750fb: merge calcPLL and getPllValue into getChipClock
The getChipClock function is used only to get MXCLK frequency, which
makes most of getPllValue function unused and thus. The detection of
MXCLK frequency may be implemented directly in getChipClock rendering
getPllValue and calcPLL unused.
