airoha: remove KERNEL_LOADADDR from airoha_an7583-evb device definition
Delete the KERNEL_LOADADDR assignment from the airoha_an7583-evb device definition.
The kernel load address is now centrally managed in image Makefile with, just using default load address:
loadaddr-$(CONFIG_TARGET_airoha_an7583) := 0x80200000
This ensures the load address configuration is maintained in a single location.
Removing the duplicate assignment prevents confusion and potential misconfiguration.
