clk: renesas: r9a07g044: Add clock and reset entries for CRU
Add CRU clock and reset entries to CPG driver.
CRU_SYSCLK and CRU_VCLK clocks need to be turned ON/OFF in particular
sequence for the CRU block hence add these clocks to
r9a07g044_no_pm_mod_clks[] array and pass it as part of CPG data for
both RZ/G2L and RZ/V2L SoCs.
