Subject: [PATCH] x86, boot: Remove multiple copy of static function sanitize_boot_params()

Kernel build reporting warnings:
 'sanitize_boot_params' defined but not used [-Wunused-function]

at below files:
arch/x86/boot/compressed/cmdline.c
arch/x86/boot/compressed/error.c
arch/x86/boot/compressed/early_serial_console.c
arch/x86/boot/compressed/acpi.c

That's due to they each include misc.h which includes a definition
of sanitize_boot_params().

Remove the inclusion from misc.h and have the c file including
bootparam_utils.h directly.
