Most Maxim PMIC regulator drivers are for sub-devices of Multi-Function
Devices with drivers under drivers/mfd. But for many of these, the same
object file name was used for both the MFD and the regulator drivers.

Having 2 different drivers with the same name causes a lot of confusion
to Kbuild, specially if these are built as module since only one module
will be installed and also exported symbols will be undefined due being
overwritten by the other module during modpost.

For example, it fixes the following issue when both drivers are module:

$ make M=drivers/regulator/
  ...
  CC [M]  drivers/regulator//max14577.o
  Building modules, stage 2.
  MODPOST 1 modules
WARNING: "maxim_charger_calc_reg_current" [drivers/regulator//max14577.ko] undefined!
WARNING: "maxim_charger_currents" [drivers/regulator//max14577.ko] undefined!

The vexpress regulator implementation is currently just called vexpress.
This is a problem because it clashes with another module with the same
name in hardware monitors.

This patch renames the vexpress regulator implementation to
vexpress-regulator so that there will be no clash in the module namespace.

The max77686 and max77802 regulator drivers are for sub-devices of a MFD
driver for some PMIC blocks. But the same object file name (max77686.o)
was used for both the common MFD driver and the max77686 regulator one.

This confuses kbuild if both drivers are built as module causing the MFD
driver to not be copied when installing the modules.

Also, max77{686,802} are a quite generic name for MFD subdevices drivers
so it is better to rename them to max77{686,802}-regulator like it's the
case for most regulator drivers.

2) No two regulators can be enabled at the same time. Use mutex in
