Also simplify the error handling to start unwind from the place
regulator_register fails.
No need to check rdev[i] is NULL or not before calling regulator_unregister.
regulator_unregister is safe if rdev is NULL,

All the drivers that need delay for the regulator voltage output voltage to
stabilize after being enabled or after being set to a new value has been
converted to implement enable_time and set_voltage_time_sel callbacks.
Then regulator core will take care of the necessary delay.
For the drivers that don't need the delay, don't need to include linux/delay.h.
This patch removes the unneeded include of linux/delay.h in regulator drivers.

Since commit 8ac0e95 "regulator: core: Support setting suspend_[mode|voltage]
if set_suspend_[en|dis]able is NULL", now the regulator core can properly
handle the case set_suspend_enable callback is NULL.

If is_enabled callback is not implemented, the core assumes that the regulator
is on.
This is simpler than having a hack to retrun 1 in max8997_reg_is_enabled() if
max8997_get_enable_register() returns -EINVAL.

Integer division may truncate the result.
Use DIV_ROUND_UP to ensure new voltage setting falls within specified range.
Also properly handle the case min_vol < desc->min to ensure we don't return
negative value for selector.

commit 4ca1e1d "regulator: Convert 88pm8607 to set_voltage_sel" accidentally
changed the value writing to vol_reg.
What we want is to write val instead of selector to vol_reg.

Also rename get_current_limit and set_current_limit callbacks
to max8997_get_current_limit and max8997_set_current_limit for

Add irq domain support for max8997 interrupts. The reverse mapping method
used is linear mapping since the sub-drivers of max8997 such as regulator
and charger drivers can use the max8997 irq_domain to get the linux irq
number for max8997 interrupts. All uses of irq_base in platform data and
max8997 driver private data are removed.

There's no need to implement set_voltage() as there is only a very small
range of selectors for the regulators in the WM8994 and the voltages are
not expected to vary frequently at runtime.
