ARM: DRA7: Set serial number environment variable

Browse source 
This patch populates serial number environment variable from
die_id_0 and die_id_1 register values for DRA7xx boards.

The function is added in omap common code so that this can be re-used.

Serial# environment variable will be useful to show correct
information in "fastboot devices" commands.
