Merge series "Add pca9450 driver" from Robin Gong <yibin.gong@nxp.com>:

Add pca9450 driver for i.mx8mn-evk board. PCA9450A/B/C supported now.
Please refer to below link for PCA9450 datasheet:
https://www.nxp.com/docs/en/data-sheet/PCA9450DS.pdf

v2:
  1. rebase with the latest code to use linear_ranges helper instead.
  2. address Frieder's comments, such as dulipcated buck4 description,
     debug info added etc.

Regulator nodes should be named to BUCK_<number> and LDO_<number>. The
definition for each of these nodes is defined using the standard
binding for regulators at
Documentation/devicetree/bindings/regulator/regulator.txt.
Datasheet is available at
https://www.nxp.com/docs/en/data-sheet/PCA9450DS.pdf
#The valid names for PCA9450 regulator nodes are:
#BUCK1, BUCK2, BUCK3, BUCK4, BUCK5, BUCK6,
#LDO1, LDO2, LDO3, LDO4, LDO5
#Note: Buck3 removed on PCA9450B and connect with Buck1 on PCA9450C.
