x86: Do not include <asm/bootparam.h> in several files Remove the include statement for <asm/bootparam.h> from several files that don't require it and limit the exposure of those definitions within the Linux kernel code.

x86/compressed/acpi: Move EFI kexec handling into common code Future patches for SEV-SNP-validated CPUID will also require early parsing of the EFI configuration. Incrementally move the related code into a set of helpers that can be re-used for that purpose. In this instance, the current acpi.c kexec handling is mainly used to get the alternative EFI config table address provided by kexec via a setup_data entry of type SETUP_EFI. If not present, the code then falls back to normal EFI config table address provided by EFI system table. This would need to be done by all call-sites attempting to access the EFI config table, so just have efi_get_conf_table() handle that automatically.
