board:samsung:common: set envs with board unified information
This patch sets envs that describe board information.
The following envs are set: soc_id, soc_rev, board_rev.
Based on this information, if CONFIG_OF_LIBFDT is enabled,
the 'fdtfile' env is set as:
fdtfile=${soc_family}${soc_id}-${board}.dtb
The generated envs are intenionally not saved to persistent storage.
