clk: samsung: Add clock PLL support for ARTPEC-8 SoC

Add below clock PLL support for Axis ARTPEC-8 SoC platform:
- pll_1017x: Integer PLL with mid frequency FVCO (950 to 2400 MHz)
             This is used in ARTPEC-8 SoC for shared PLL

- pll_1031x: Integer/Fractional PLL with mid frequency FVCO
             (600 to 1200 MHz)
             This is used in ARTPEC-8 SoC for Audio PLL

FOUT calculation for pll_1017x and pll_1031x:
FOUT = (MDIV x FIN)/(PDIV x 2^SDIV) for integer PLL
FOUT = (((MDIV + KDIV)/65536) x FIN)/(PDIV x 2^SDIV) for fractional PLL
