mfd: Add LP3943 MFD driver

LP3943 has 16 output pins which can be used as GPIO expander and PWM generator.

* Regmap I2C interface for R/W LP3943 registers

* Atomic operations for output pin assignment
The driver should check whether requested pin is available or not.
If the pin is already used, pin request returns as a failure.
A driver data, 'pin_used' is checked when gpio_request() and
pwm_request() are called. If the pin is available, then pin_used is set.
And it is cleared when gpio_free() and pwm_free().

* Device tree support
Compatible strings for GPIO and PWM driver.
LP3943 platform data is PWM related, so parsing the device tree is
implemented in the PWM driver.

binding with max14577_i2c_parse_dt().

The MAXIM 14577 chip contains Micro-USB Interface Circuit and Li+ Battery
Charger. It contains accessory and USB charger detection logic. It supports
USB 2.0 Hi-Speed, UART and stereo audio signals over Micro-USB connector.

The battery charger is compliant with the USB Battery Charging Specification
Revision 1.1. It has also SFOUT LDO output for powering USB devices.

mfd: Move ssbi driver into drivers/mfd

There is no reason for ssbi to have its own top-level driver directory
when the only users of this interface are all MFD drivers. The only
mainline driver using it at the moment (PM8921) is marked broken and in
fact does not compile. I have verified that fixing the trivial build
breakage in pm8921 links in the new ssbi code just fine, but that
can be a separate patch.
