a6324709ab regulator: ab8500-ext: Add support for AB8505/AB9540 
The external regulator driver checks for old AB8500 HW
to apply a fix. This patch adds a check to see that
it is a AB8500 (not AB8505/AB9540).

18bc2b3930 regulator: ab8500-ext: Add HW request support 
Support for HW request is added in the external regulator
driver. A flag in the board configuration can be set to
let HW control the regulator when there is no SW request.
This means that the regulator will be put in high power
mode when there is a SW request and in HW-request mode
otherwise.

d1a820011b regulator: ab8500-ext: New driver to control external regulators 
The ABx500 is capable of controlling three external regulator supplies.
Most commonly on and off are supported, but if an external regulator
chipset or power supply supports high-power and low-power mode settings,
we can control those too.
