clk: renesas: r9a07g044: Update multiplier and divider values for PLL2/3
[ Upstream commit b289cdecc7c3e25e001cde260c882e4d9a8b0772 ]
As per the HW manual (Rev.1.00 Sep, 2021) PLL2 and PLL3 should be
1600 MHz, but with current multiplier and divider values this resulted
to 1596 MHz.
This patch updates the multiplier and divider values for PLL2 and PLL3
so that we get the exact (1600 MHz) values.
