[PATCH v2 4/6] clk: sunxi-ng: d1: Mark cpux clock as critical

From: András Szemző <szemzo.andras@gmail.com>

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.
