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)
