add pmic pca9451a support
Merge series from Joy Zou <[email protected]>: The patchset supports pmic pca9451a. For the details, please check the patch commit log. --- Changes in v5: - adjust gpio@22 to the front of pmic@25. Changes in v4: - modify the comment for uSDHC but not i2c. Changes in v3: - modify the dts voltags constraints. - remove unnecessary changes in driver code. - modify commit message. - add tag for dt-bindings. Changes in v2: - drop old part support.
