Exynos 5250 boards (snow, spring) use the I2C driver but Exynos 5420 boards
cannot due to a hardware design decision. Select the correct driver to use
in each case.

Unfortunately on Pit the AP has no direct access to the tps65090 but must
talk through the EC (over SPI) to the EC's I2C bus.
When driver model supports PMICs this will be relatively easy. In the
meantime the best approach is to duplicate the driver. It will be refactored
once driver model support is expanded.

It is redundant to use 'PFUZE100_PMIC' as the PMIC name because we already
know it is a PMIC.
Call it simply 'PFUZE100' instead.

Since p->bus is unsigned checking for negative values
is optimized away. Since bus is already used as an argument
use tmp. While at it, don't declare variables in the middle
of a function.

The function tps65090_init checks the i2c bus of p->bus. However

The current pmic i2c code assumes the current i2c bus is
the same as the pmic device's bus. There is nothing ensuring
that to be true. Therefore, select the proper bus before performing
a transaction.

This adds driver support for the TPS65090 PMU. Support includes
hooking into the pmic infrastructure so that the pmic commands
can be used on the console. The TPS65090 supports the following
functionality:
- fet enable/disable/querying
- getting and setting of charge state
Even though it is connected to the pmic infrastructure it does
not hook into the pmic charging charging infrastructure.
The device tree binding is from Linux, but only a small subset of
functionality is supported.

The LTC3676 PMIC includes four DC/DC converters, and three 300mA
LDO Regulators (two Adjustable). The DC/DC converters are adjustable based
on a resistor devider (board-specific).
This adds support for the LTC3676 by creating a namespace unique init function
that uses the PMIC API to allocate a pmic and defines the registers.

Issues:
- reading i2c data by passing u16 pointer causes errors in read data.
- max17042 status register fields have not only Power On Reset meaning
so using proper mask is required.
Changes:
- read i2c data to type u32 instead of u16 - avoids buffer overflow
- compare FG status register using mask not just one bit value
- add checking return value to functions fg read/write
- add model lock and model check count
- add debug msg

commit 21144298 (power: twl6035: add palmas PMIC support)
introduced twl6035_i2c_[read|write]_u8
Then, commit dd23e59d (omap5: pbias ldo9 turn on)
introduced palmas_[read|write]_u8 for precisely the same access
function. TWL6035 belongs to the palmas family, so instead of having
an twl6035 API, we could use an generic palmas API instead.
To stay consistent with the function naming of twl4030,6030 accessors,
we use palmas_i2c_[read|write]_u8
