clk: imx: fracn-gppll: support integer pll The fracn gppll could be configured in FRAC or INTEGER mode during hardware design. The current driver only support FRAC mode, while this patch introduces INTEGER support. When the PLL is INTEGER pll, there is no mfn, mfd, the calculation is as below: Fvco_clk = (Fref / DIV[RDIV] ) * DIV[MFI] Fclko_odiv = Fvco_clk / DIV[ODIV] In this patch, we reuse the FRAC pll logic with some condition check to simplify the driver Signed-off-by: Peng Fan <peng.fan@nxp.com> Reviewed-by: Abel Vesa <abel.vesa@linaro.org> Link: https://lore.kernel.org/r/20230403095300.3386988-4-peng.fan@oss.nxp.com Signed-off-by: Abel Vesa <abel.vesa@linaro.org>
