Subject: [PATCH v3 1/2] regulator: dt-bindings: pca9450: Add nxp,pf9453
 compatible string

Add the compatible string "nxp,pf9453" for the PF9453 regulator. The PF9453
is similar to the PCA9460 but supports only LDO1, LDO2, LDO_SVNS, and
BUCK[1-4].

Restrict LDO and BUCK numbers for nxp,pf9453 and keep the same restriction
for other compatible strings.

Signed-off-by: Frank Li <Frank.Li@....com>

change from v2 to v3
- LDO_SNVS to LDO-SNVS
