[PATCH 2/2] devicetable-offsets: Get struct cpu_feature from a device-id header

[Sasha Levin <sashal@kernel.org>]

Since commit cdfdbc11552b ("Move struct cpu_feature to
<linux/cpufeature.h>"), devicetable-offsets.c includes
<linux/cpufeature.h>, which includes <asm/cpufeature.h> on architectures
that select GENERIC_CPU_AUTOPROBE. On loongarch and mips that header
pulls in <asm/elf.h>, and from there <linux/fs.h> and <linux/mmzone.h>,
which need <generated/bounds.h>. devicetable-offsets.c is built before
that header is generated, so even defconfig fails on both:

  include/linux/page-flags-layout.h:6:10: fatal error: generated/bounds.h: No such file or directory

Move struct cpu_feature to <linux/device-id/cpu_feature.h>, next to the
other device id types, and include that from <linux/cpufeature.h>,
devicetable-offsets.c and file2alias.c.
