arm64: dts: amlogic: t7: khadas-vim4: add PWM-driven status LED

This commit adds a new pwm-leds node with a heartbeat trigger to the VIM4
board devicetree. It also enables the pwm_ao_cd controller and reorders the
xtal-clk node.

Will this child node name trigger a devicetree schema validation warning?

The PWM LEDs device tree binding schema restricts child node names using a
pattern property. It expects child nodes to match the regular expression
^led(-[0-9a-f]+)?$.

Since this node is named status, will dtbs_check treat it as an invalid
additional node?
