env: mmc: add redundancy support in mmc_offset_try_partitionWIP/2020-07-24-misc-env-improvements
Manage 2 copy at the end of the partition selected by config
"u-boot,mmc-env-partition" to save the U-Boot environment,
with CONFIG_ENV_SIZE and 2*CONFIG_ENV_SIZE offset.
This patch allows to support redundancy (CONFIG_ENV_OFFSET_REDUND).
