clk: imx: pllv4: Fix SPLL2 MULT range

[ Upstream commit 3f0cdb945471f1abd1cf4d172190e9c489c5052a ]

The SPLL2 on iMX8ULP is different with other frac PLLs, it can
support VCO from 650Mhz to 1Ghz. According to RM, the MULT is
using a range from 27 to 54, not some fixed values. If using
current PLL implementation, some clock rate can't be supported.

Fix the issue by adding new type for the SPLL2 and use MULT range
to replace MULT table
