fix for "error: implicit declaration of function 'devres_alloc'" in Mar9 tree

[Paul Gortmaker <paul.gortmaker@windriver.com>]

There are a couple builds showing:

drivers/base/regmap/regmap.c:331: error: implicit declaration of function 'devres_alloc'
drivers/base/regmap/regmap.c:338: error: implicit declaration of function 'devres_add'
drivers/base/regmap/regmap.c:340: error: implicit declaration of function 'devres_free'
drivers/base/regmap/regmap.c:421: error: implicit declaration of function 'dev_err'
make[4]: *** [drivers/base/regmap/regmap.o] Error 1

This is caused by commit 19694b5ea1d3 which just appeared in today's next
tree exposing another implicit device.h user.  Just a quick note that I'll
take care of it by adding regmap.c to the below commit.

Paul.

    device.h: cleanup users outside of linux/include (C files)
    
    For files that are actively using linux/device.h, make sure
    that they call it out.  This will allow us to clean up some
    of the implicit uses of linux/device.h within include/*
    without introducing build regressions.
