Subject: [PATCH] regulator: pca9450: Support PWM mode also for pca9451a

Previous commit 548d770c330c ("regulator: pca9450: Add support for mode
operations") added support for setting forced PWM mode on the buck
regulators for pca9450a and pca9450bc parts. However part pca9451a also
supports this feature, thus add support for it.

Fixes: 548d770c330c ("regulator: pca9450: Add support for mode operations")
