v3: Only define ENV_IS_NOWHERE if env is not in MMC, NAND, FAT, and SPI_FLASH v2: Move this option to be on a per-board basis Add config for socfpga_cyclone5 and socfpga_arria5

Actually... if we decided that position of u-boot environment is board-specific, size should be board-specific, too.
But it might be better to just define
#define ENV_IN_MMC_SECTOR_1
in each board, and have the common code in socfpga_common.h... so that we can change environment size for all boards using "after mmc" layout, for example.
Ouch and 4K is way too small. Pavel
