The omap5_uevm platform has eMMC, and it makes sense to say that our default env storage shall reside there. Other platforms may not, so move this choice to the EVM config. In addition, we should provide some way to partition the flash for later usage, so take advantage of the GPT partition table support code and allow that to be setup with some reasonable defaults.
