clk: renesas: r8a779f0: Fix RSW2 clock divider
According to Section 8.1.2 Figure 8.1.1 ("Block Diagram of CPG"), Note
22 ("RSW2 divider"), and Table 8.1.4d ("Lists of CPG clocks generated
from CPGMA1"), the RSwitch2 and PCI Express clock is generated from PLL5
by dividing by two, followed by the RSW2 divider. As PLL5 runs at 3200
MHz, and RSW2 is fixed to 320 MHz, the RSW2 divider must be 5.
Correct the parent and the fixed divider.
