f222447ea1 misc: vexpress: Fix sparse non static symbol warnings
Fixes the following sparse warnings:

drivers/misc/vexpress-syscfg.c:133:22: warning:
 symbol 'vexpress_syscfg_regmap_config' was not declared. Should it be static?
drivers/misc/vexpress-syscfg.c:279:5: warning:
 symbol 'vexpress_syscfg_probe' was not declared. Should it be static?

b86e1926be mfd: vexpress: fix error handling vexpress_syscfg_regmap_init()
This function should be returning an ERR_PTR() on failure instead of
NULL.  Also there is a use after free bug if regmap_init() fails because
we free "func" and then dereference doing the return.

974cc7b934 mfd: vexpress: Define the device as MFD cells
This patch - finally, after over 6 months! :-( - addresses
Samuel's request to split the vexpress-sysreg driver into
smaller portions and define the device in a form of MFD
cells:

* LEDs code has been completely removed and replaced with
  "gpio-leds" nodes in the tree (referencing dedicated
  GPIO subnodes in sysreg - bindings documentation updated);
  this also better fits the reality as some variants of the
  motherboard don't have all the LEDs populated

* syscfg bridge code has been extracted into a separate
  driver (placed in drivers/misc for no better place)

* all the ID & MISC registers are defined as sysconf
  making them available for other drivers should they need
  to use them (and also to the user via /sys/kernel/debug/regmap
  which can be helpful in platform debugging)
