env_fat: use get_device_and_partition() during env save and load
Use get_device_and_partition() is better since: 1. It will call the device initialize function internally. So we can remove the mmc intialization code to save many lines. 2. It is used by fatls/fatload/fatwrite. So saveenv & load env should use it too. 3. It can parse the "D:P", "D", "D:", "D:auto" string to get correct device and partition information by run-time. Also we remove the FAT_ENV_DEVICE and FAT_ENV_PART. We use a string: FAT_ENV_DEVICE_AND_PART. For at91sam9m10g45ek, it is "0". That means use device 0 and if: a)device 0 has no partition table, use the whole device as a FAT file system. b)device 0 has partittion table, use the partition #1. Refer to the commit: 10a37fd7a4 for details of device & partition string. Signed-off-by: Josh Wu <josh.wu@atmel.com> Reviewed-by: Stephen Warren <swarren@nvidia.com>
