SPEAr: clk: Add VCO-PLL Synthesizer clock
All SPEAr SoC's contain PLLs. Their Fout is derived based on following equations
- In normal mode
vco = (2 * M[15:8] * Fin)/N
- In Dithered mode
vco = (2 * M[15:0] * Fin)/(256 * N)
pll_rate = vco/2^p
vco and pll are very closely bound to each other,
"vco needs to program: mode, m & n" and "pll needs to program p",
both share common enable/disable logic and registers.
This patch adds in support for this type of clock.
