Subject: [PATCH 66/79] always enable FW_LOADER unless EMBEDDED=y

From: Adrian Bunk <bunk@...nel.org>

James Bottomley recently discovered that we have
{request,release}_firmware() dummies for the case of the actual
functions not being available and has a fix for the bug that was
actually causing build errors for built-in users with
CONFIG_FW_LOADER=m.

But now missing selects on FW_LOADER are no longer visible at
compile-time at all and can become runtime problems.

FW_LOADER is infrastructure with relatively small codesize we can safely
enable for everyone, and only for people who really need small kernels
(and can be expected to know what they are doing) it matters being able
to disable it.

This patch therefore always sets FW_LOADER=y and allows users only to
disable it with EMBEDDED=y.

As a bonus, we can then get rid of all "select FW_LOADER" plus the due
to it required "depends on HOTPLUG" which removes some complexity from
our Kconfig files.
