Regulator '*-supply' properties are always a single phandle, so
'maxItems: 1' or a $ref is not necessary. All that's needed is either
'true' or an optional 'description'. Following this clean-up, the
meta-schema will enforce this pattern.

There's one case in tree with 'innolux,n156bge-l21' having 2 phandles.
This appears to be a mistake or abuse of simple-panel as it's 2 different

of: Make of_dma_get_range() work on bus nodes

Since the "dma-ranges" property is only valid for a node representing a
bus, of_dma_get_range() currently assumes the node passed in is a leaf
representing a device, and starts the walk from its parent. In cases
like PCI host controllers on typical FDT systems, however, where the PCI
endpoints are probed dynamically the initial leaf node represents the
'bus' itself, and this logic means we fail to consider any "dma-ranges"
describing the host bridge itself. Rework the logic such that
of_dma_get_range() also works correctly starting from a bus node
containing "dma-ranges".

While this does mean "dma-ranges" could incorrectly be in a device leaf
node, there isn't really any way in this function to ensure that a leaf
node is or isn't a bus node.
