Currently, set invalid mode setting for shared mode regulators may change
sm->lp_mode_req flag. This patch ensures we don't set lp_mode_req flag to wrong
status if set_mode() fails.
This patch includes some clean up, and these changes makes this patch looks like
code refactor. The clean up is mainly to avoid adding ugly code to handle
failure paths.

LDO8 of Palma device like tps65913 support the tracking mode
on which LDO8 track the SMPS45 voltage when SMPS45 is ON
and use the LDO8.VOLTAGE_SEL register when SMPS45 is OFF.
On track mode, the steps of voltage change for LDO8 is 25mV
where in non-tracking mode it is 50mV. Set the steps accordingly.
Number of voltage count is still same for both the cases.

Attempted to differentiate between regulator_get() with an actual

However, ret value supplied by regulator_dev_lookup() is being
ignored by regulator_get(). So, exit with the appropriate return value.

Thus we can complete remove the unnecessary checking for ab9540 and ab8540.

This is required to avoid a forward declaration because now we call

Regulator drivers may specify regulator_desc->supply_name which
regulator_register() will use to find the supply node for a regulator.
If no supply was specified in the device tree or the supply has yet
to be registered regulator_register() will fail, deferring the probe
of the regulator. In the case where no supply node was specified in the
device tree, there is no supply and it is pointless to try and find one
later, so go ahead and add the regulator without the supply.
