This patch adds redundant environment for environment in SPI flash. I took env_flash.c as an example and slightly modified it. Apart from adapting things to SF, I also slightly changed the decision logic to use area 2 as a default in case the flags are wrong.
I did not add a section for CONFIG_ENV_IS_IN_SPI_FLASH in environment.h because I did not understand if this is desired and/or needed. So to use the feature, one has to set CONFIG_ENV_OFFSET_REDUND _and_ CONFIG_SYS_REDUNDAND_ENVIRONMENT.
I checked it by powering off my board several times during flash erase or write, because I do not know if there are other stress test scenarios.
