Convert these boards to use a text environment.
For the boards check, the only differences are extra spaces after the semicolons in 'dfu_alt_info_ram' and 'partitions', both of which are permitted.
Add in the special boot command for old kernels, dropping the unnecessary and confusing hex prefixes.

Changes in v2: - Keep bootcmd_sunxi_compat if OLD_SUNXI_KERNEL_COMPAT is enabled
