regulator: palmas: get regulators node from parent node only

The device tree binding of Palmas regulator driver says as:

palmas_pmis {
	compatible = "ti,palmas-pmic";
	...
	regulators {
		...
	}
};

In this "regulators" subnode is expected to be part of parent node, not
the outside of parent node. Hence to get the regulator node, the correct
call is of_get_child_by_name() rather than of_find_node_by_name() which
actually searches the "regulators" node from the parent node to end of DTS
file.

regulator: palmas: Remove wrong comment for the equation calculating num_voltages

Current equation on the comment is wrong.
For linear mapping starting from 0, the equation is (maxV-minV)/stepV + 1.
Since the linear mapping for PALMAS is not all starting from 0, the equation
on the comment is not useful and misleading. Thus remove it.

As per datasheet (Referred TPS65913), the on-time for LDO is
500micro second. If LDO6 is in vibrator mode then the on-time
is 2000us.

Set the enable_time on regulator descriptor accordingly.

Palmas rails like LDOs, SMPSs, REGENs, SYSENs can be enable and disable
by register programming through I2C communication as well as it can be
enable/disable with the external control input ENABLE1, ENABLE2 and NSLEEP.

Add support for configuring these rails to be controlled by external control
inputs. This is require to configure the rail's control register as well as
configuration of resource register.

Provide the external input names through parameter "roof-floor". Updated the
DT binding document to details different value of the roof-floor.
