i2c_driver does not need to set an owner because i2c_register_driver()

The max14577 MFD cells do not have any resources so the IRQ domain

This patch prepares for changing the max14577 charger driver to allow
configuring battery-dependent settings from DTS.
The patch moves from regulator driver to MFD core driver and exports:
- function for calculating register value for charger's current;
- table of limits for chargers (MAX14577, MAX77836).
Previously they were used only by the max14577 regulator driver. In next
patch the charger driver will use them as well. Exporting them will
reduce unnecessary code duplication.

Add a "maxim,max14577-charger" of_compatible to the mfd_cell so the
MFD child device (the charger) will have its own of_node set. This will
be used by the max14577 charger driver in next patches to obtain battery
configuration from DTS.

During suspend the IRQ should be disabled even if this is not a wakeup
source. This is a proper way of fixing the IRQ handling issue during
resume (IRQ handler fails because I2C bus did not resume yet).
When device is suspended and max14577 interrupt is signaled the irq chip
will try to handle it regardless of wakeup source. Device could be woken
up by different IRQ but still the IRQ handler will try to read the
registers over I2C bus and fail because I2C bus won't be ready yet:
max14577 2-0025: Failed to read IRQ status: -5

Add support for MAX77836 chipset to the max14577 extcon driver. The
MAX77836 MUIC has additional interrupts (VIDRM, ADC1K) so IRQ handling
is split up into two functions: max14577_parse_irq() and
max77836_parse_irq().

Add Maxim 77836 support to max14577 driver. The chipsets have same MUIC
component so the extcon, charger and regulators are almost the same. The
MAX77836 however has also PMIC and Fuel Gauge.
The MAX77836 uses three I2C slave addresses and has additional interrupts
(related to PMIC and Fuel Gauge). It has also Interrupt Source register,
just like MAX77686 and MAX77693.
The MAX77836 PMIC's TOPSYS and INTSRC interrupts are reported in the
PMIC block. The PMIC block has different I2C slave address and uses own
regmap so another regmap_irq_chip is needed.
Since we have two regmap_irq_chip, use shared interrupts on MAX77836.
This patch adds additional defines and functions to the max14577 MFD core
driver so the driver will handle both chipsets. Also this patch replaces
"0x1 << N" with BIT(N) in defines for register masks.

This patch continues the preparation for adding support for MAX77836
device to existing max14577 driver.
Add enum for types of devices supported by this driver. The device type
will be detected by matching of_device_id, or i2c_device_id as a
fallback.
The patch also moves to separate function the code related to displaying
DeviceID register values.

Add of_compatible ("maxim,max14577-muic") to the mfd_cell for extcon
driver. If entry with such compatible is present in the DTS, the extcon
driver will have of_node set.
This may be useful for extcon consumers and it is documented in
bindings documentation.

This patch adds max14577 core/irq driver to support MUIC(Micro USB IC)
device and charger device and support irq domain method to control
internal interrupt of max14577 device. Also, this patch supports DT
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.
