Subject: [PATCH v3 2/7] dt-bindings: mfd: brcm,bcm59056: Add compatible for
 BCM59054

The BCM59054 MFD is fairly similar to the BCM59056, and will use
the same driver. Add compatible and specify the allowed regulator
nodes.

Signed-off-by: Artur Weber <aweber.kernel@...il.com>

Changes in v3:
- Split regulator node into separate file
- Removed quotes around compatible
