xtensa: drop CONFIG_EMBEDDED_RAMDISK
Remove Kconfig entries, boot subdirectory, dependencies from other boot-* Makefiles, and sections from ld scripts. Remove stale redboot code that used to pass initrd addresses in a3 and a4 to _start. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>
