kexec_file: remove unused arch_kexec_locate_mem_hole hook
No architecture provides an implementation of
arch_kexec_locate_mem_hole(). Use kexec_locate_mem_hole() directly
and remove the unused fallback wrapper from the kexec header.
This simplifies the kexec memory allocation path without changing
its behavior. No functional changes intended.
The arch hook was introduced by commit f891f19736bd ("kexec_file: Allow
archs to handle special regions while locating memory hole"), and its
last user was removed by commit 6e5250eaa665 ("powerpc/crash: use
generic APIs to locate memory hole for kdump").
