[PATCH v14 04/15] stm32mp1: Add a node for the FWU metadata device

[Sughosh Ganu]

The FWU metadata structure is accessed through the driver model
interface. On the stm32mp157c dk2 and ev1 boards, the FWU metadata is
stored on the uSD card. Add the fwu-mdata node on the u-boot specifc
dtsi file for accessing the metadata structure.
