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

When programming PLL, should disable Hardware control select to make PLL
controlled by register, not hardware inputs through OSCPLL.

The Fvco should be range 2.4GHz to 5GHz, the original table voilate the
spec, so update the table to fix it.

According to Reference Manual:
000b - Divide by 1
001b - Divide by 1
010b - Divide by 2
011b - Divide by 3
100b - Divide by 4
101b - Divide by 5
110b - Divide by 6
111b - Divide by 7
So only need increase rdiv by 1 when the register value is 0.

The PLL parameters in rate table should be directly compared with
those read from PLL registers instead of the cooked ones.

This PLL module is a Fractional-N synthesizer,
supporting 30-bit numerator and denominator. Numerator is a signed
number. It has feature to adjust fractional portion of feedback
divider dynamically. This fracn gppll is used in i.MX93.
