[PATCH 1/2] ARM: mxs: Add serial: Search for specific ocotp nodes

[Fabio Estevam]

From: Fabio Estevam <festevam at denx.de>

Per mxs-ocotp.yaml, "fsl,ocotp" is not a valid entry.

"fsl,ocotp" is only used to indicate the location of the
struct device_node that points to the ocotp node.

Search for the specific "fsl,imx28-ocotp" and "fsl,imx23-ocotp"
instead and remove the undocumented "fsl,ocotp" fallback.
