sunxi: configs: enable power LEDs on 64-bit boards

We recently gained a simple way to enable a power LED very early in the
SPL boot, through simple Kconfig variables.

Add those symbols to those boards' defconfigs where the DT indicates a
default-on power LED. The number used is <port bank> * 32 + <pin no>,
an active low setup means CONFIG_SPL_SUNXI_LED_STATUS_ACTIVE_HIGH must be
undefined.

This will light up the power LED very early in the (SPL) boot phase on
those 64-bit boards.
