Don't store pointers to regulator_dev returned by
devm_regulator_register() in allocated memory in state container. They
aren't used anywhere outside of max77693_pmic_probe() function.
This change allows removing completely the 'struct max77693_pmic_dev'
state container as none of its fields are used outside of probe.

of_find_node_by_name walks the allnodes list, and can thus walk
outside of the parent node. Use of_get_child_by_name instead.

NULL assignment corrupts the error pointer and is not

The implementation in of_regulator_match() already ensures match->init_data is
not NULL for all matched cases if the return value of of_regulator_match() > 0.
Thus remove NULL test for rmatch[i].init_data.
This patch also fixes the condition for loop iteration.
The for loop should iterate "matched" times rather than ARRAY_SIZE(regulators)
because we only allocate "matched" number of entries for rdata.
Though in most cases, "matched" == ARRAY_SIZE(regulators).

This patch adds new regulator driver to support max77693 chip's regulators.
max77693 has two linear voltage regulators and one current regulator which
can be controlled through I2C bus. This driver also supports device tree.
