Subject: kexec: remove unnecessary arch_kexec_kernel_image_load()
Date: Tue, 7 Mar 2023 16:44:16 -0600
arch_kexec_kernel_image_load() only calls kexec_image_load_default(), and
there are no arch-specific implementations.
Remove the unnecessary arch_kexec_kernel_image_load() and make
kexec_image_load_default() static.
No functional change intended.
