MLK-20955 imx8qm: delete power-domains for lpuart0 on xen 

To U-Boot on DomU, the lpuart0 is replaced with a xen paravirtual
consol driver, but reused the previous lpuart node. However
there is an power-domains entry in lpuart0 which will call
power_domain_on and failed to probe xen paravirtual driver,
because of recent change:
commit 8524ca764d8f("MLK-20945-2 dm: device: Check the power up result in probe ")

So remove the power-domains entry in lpuart0 to let DomU U-Boot could
output again.
