[PATCH v2 3/4] ARM: dts: aspeed: santabarbara: Adjust LED configuration

Update LED definitions to match changes in the hardware spec. Add a
power-fault LED on GPIOB5 and relocate the ID LED to GPIOQ4 via the
CPLD. The ID LED now shares the power LED: it blinks when ID is active
and otherwise indicates power state with logic controlled by the CPLD.
Retain the 'fp_id_amber' label so /sys/class/leds/fp_id_amber remains
valid for existing users.
Add a 'bmc_ready_noled' LED on GPIOB3 with GPIO_TRANSITORY to ensure its
state resets on BMC reboot.
