Changes in v2:
-Rebase
Changes in v3:
-Add support for all dldo and aldo-s
-Add Kconfig option to select building AXP221 and to select voltage of
dldo and aldo-s
Changes in v4:
-Add axp221_setbits helper function
-Use symbolic names for enabled bits in CTRL1 - CTRL3 registers
The pmic_spi_free function isn't ever used, and as the frameworks stand
today, cannot be, so remove it. Integrate the probe function into
pmic_reg as it's not really a "probe" today. Finally, add an err label
for the common failure cases.

Currently uboot wrongly uses 25mV / step for dcdc3, this is a copy and paste
error introduced when adding the axp152_mvolt_to_target during review of the
axp152.c driver. This results in u-boot setting Vddr to 2.3V instead of 1.5V.

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.

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
