The registration of the "leds-gpio" device was using
"vexpress_sysreg_dev" as a parent before it was actually
set to something different than NULL.

Trivial fix by reordering the code.

Pull MFS updates from Samuel Ortiz:
 "This is the MFD pull request for the 3.9 merge window.

  No new drivers this time, but a bunch of fairly big cleanups:

   - Roger Quadros worked on a OMAP USBHS and TLL platform data
     consolidation, OMAP5 support and clock management code cleanup.

   - The first step of a major sync for the ab8500 driver from Lee
     Jones.  In particular, the debugfs and the sysct interfaces got
     extended and improved.

   - Peter Ujfalusi sent a nice patchset for cleaning and fixing the
     twl-core driver, with a much needed module id lookup code
     improvement.

   - The regular wm5102 and arizona cleanups and fixes from Mark Brown.

   - Laxman Dewangan extended the palmas APIs in order to implement the
     palmas GPIO and rt drivers.

   - Laxman also added DT support for the tps65090 driver.

   - The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra
     and Darren Hart.

   - Linus Walleij patchset for the ab8500 driver allowed ab8500 and
     ab9540 based devices to switch to the new abx500 pin-ctrl driver.

   - The max8925 now has device tree and irqdomain support thanks to
     Qing Xu.

   - The recently added rtsx driver got a few cleanups and fixes for a
     better card detection code path and now also supports the RTS5227
     chipset, thanks to Wei Wang and Roger Tseng."

The vexpress_sysreg_init() is a core_initcall() already and it can
trigger the early initialisation if a matching node is found. This patch
allows the SoC code to avoid calling vexpress_sysreg_of_early_init()
explicitly.

The LEDs on the Versatile Express motherboard are controlled
through simple memory-mapped register. This patch extends
the pseudo-GPIO controller definition for these lines and
creates generic "leds-gpio" device using them

The patch 52666298a 'mfd: vexpress-sysreg: Don't skip initialization
on probe' adds a call to vexpress_sysreg_setup from a non-__init
function, so this also has to lose its __init annotation.

The vexpress-sysreg driver does not have to be initialized
early, when the platform doesn't require this. Unfortunately
in such case it wasn't initialized correctly - master site
lookup and config bridge registration were missing. Fixed now.

CONFIG_HOTPLUG is going away as an option.  As a result, the __dev*
markings need to be removed.

This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

As the current LEDs code breaks other platform, remove it.

It shall be replaced by a generic "MMIO LEDs" driver.

This is a platform driver for Versatile Express' "system
register" block. It's a random collection of registers providing
the following functionality:

- low level platform functions like board ID access; in order to
  use those, the driver must be initialized early, either statically
  or based on the DT

- config bus bridge via "system control" interface; as the response
  from the controller does not generate interrupt (yet), the status
  register is periodically polled using a timer

- pseudo GPIO lines providing MMC card status and Flash WP#
  signal control

- LED interface for a set of 8 LEDs on the motherboard, with
  "heartbeat", "mmc0" and "cpu0" to "cpu5" as default triggers
