[PATCH v8 0/8] Add support for PMICs used on Tegra 3 devices

[Svyatoslav Ryhel]

Patch set adds basic support for PMICs used in many Tegra 3 devices.
All PMIC drivers are based on datasheets provided by vendors.
Implemented API include regulator set/get voltage enable/disable and
basic PMIC r/w capabilities.

Drivers were tested by me on LG P895 (max77663), HTC One X (TPS80032)
and ASUS TF300T (tps65911). Calculations and behavior were correct,
predictable and reproducible.

Poweroff functional will be added after this basic drivers are merged.

Changes from v7:
 - no activity for 3 weeks, no changes, re-sending

Changes from v6:
 - no changes, re-sending

Changes from v5:
 - pass tps6591x regulator children directly via udevice_id data field

Changes from v4:
 - used private structure for TPS80031 SPMS driver so that internal
   flags do not interfere with those from dm_regulator_uclass_plat
 - fixed detection on ldoln and ldousb for palmas ldo driver

Changes from v3:
 - expanded descriptions in Kconfigs for pmics and regulators
 - replaced ret with other variable name if it is not used for return
 - dropped prefixed with pmic name
 - dropped () in ~(var) type expressions
 - return dm_i2c_* output in pmic_read/write functions
 - switched to log_debug in some places
 - added descryptions for some "non obvious" functions
 - fixed tps80031 spms voltage calculation in non linear region
 - adjsuted tps65911 vio voltage calculation
 
Changes from v2:
 - removed all previously made poweroff API in favour to use sysreset
 after this patchset is accepted

Changes from v1:
 - created poweroff API for PMIC and integrated it call into do_poweroff
 - added poweroff function to submitted max77663, tps80032 and tps65911
 drivers
 - fixed registers asignments for regulators with non-numeric name
 (ldoln, ldousb, vddctrl)
