Alex Elder cdee91a044 poplar: save environment at a different offset
Change CONFIG_ENV_OFFSET for Poplar to be 1MB further into the eMMC
than before.  This puts it immediately prior to the space we are
reserving offset 0x200000-0x400000 for UEFI to save its persistent
data.  Define CONFIG_ENV_SIZE as a product of env_mmc_nblks and the
sector size, like CONFIG_ENV_OFFSET is.
