clk: renesas: r8a779g0: Fix OSC predividers
According to the table in Note 5 for the OSC clock in Table 8.1.4e
("Lists of CPG clocks generated from PLL5") of the R-Car V4H Series
Hardware User's Manual Rev. 0.54, the predividers for the OSC clock are
16 resp. 32 when using a 16.66 resp. 33.33 MHz external crystal.
Fixes: 0ab55cf1834177a2 ("clk: renesas: cpg-mssr: Add support for R-Car V4H")
