arm: mvebu: Define env_sf_get_env_addr() for all Armada boards in SPL
SPI0 CS0 Flash is mapped to address range 0xD4000000 - 0xD7FFFFFF by BootROM. Proper U-Boot removes this direct mapping. So it is available only in SPL. This applies for all 32-bit Armada BootROMs. SPL mvebu code is used only on 32-bit Armada SoCs. So move env_sf_get_env_addr() function from Turris Omnia board to common SPL mvebu code and add proper checks for SPI0 CS0.
