am335x_evm:fix mmc boot environment settings
Original patch from arago-project.org u-boot-am33x
[PATCH] am335x_evm: fix mmc boot environment settings
Commit id: 3fdd541db2ad8202476ba2c5ef22ab034c85618d
* Fixed the MMC boot environment settings to try first loading
the uImage from the FAT partition instead of the ext2 partition.
* Changed to load the kernel image a kloadaddr to avoid the need
to relocate the kernel image during boot.
* Added ip_method to mmcargs
* Use bootargs_defaults to set common variables
