app: aboot: Use target specific kernel/tags/ramdisk address

Remove the check to default address values, these default values
come from fastboot host side tool and can change. This creates strong
dependency on host side tool. Instead add a compile time feature
'ABOOT_IGNORE_BOOT_HEADER_ADDRS' to use statically defined
kernel/tags/ramdisk address, specific to each target.
