clk: sunxi-ng: d1: Mark cpux clock as critical
Some SoCs in the D1 family feature ARM CPUs instead of a RISC-V CPU. In that case, the CPUs are driven from the 'cpux' clock, so it needs to be marked as critical, since there is no consumer when DVFS is disabled. This matches the drivers for other SoCs, and the "riscv" clock in this driver.
