[PATCH 1/3] env: fat: Add support for NVME

[Fabio Estevam <festevam@gmail.com>]

Add support for retrieving the FAT environment from an NVME device, the
same way it can be retrieved from MMC, SCSI, or VIRTIO.

To use the FAT environment from an NVME device, pass
CONFIG_ENV_FAT_INTERFACE="nvme" in the defconfig.
