From: Alan Tull <atull@opensource.altera.com>
Add simple on/off regulator support for ltc2978 and
other pmbus parts supported by ltc2978.c
Signed-off-by: Alan Tull <atull@opensource.altera.com>
v2: Remove '#include <linux/regulator/machine.h>'
Only one regulator per pmbus device
Get regulator_init_data from pdata or device tree
v3: Support multiple regulators for each chip
Move most code to pmbus_core.c
fixed values for on/off
v4: fix a #endif comment
simplify probe code, remove added switch statement
remove BUG_ON(), add error message and fix num_regulators

I will add the whole list to the 'help' sections of SENSORS_LTC2978 and
SENSORS_LTC2978_REGULATOR.
For the tristate/boolean lines, I can't fit the whole list, so I will
leave them as they are. Or I could change to 'LTC2978 and compatibles' as
many others in this Kconfig have.
