arm: am57xx: Set serial# variable

Browse source 
serial# variable is used to correctly display device ID in
"fastboot devices". It also can be used further for displaying device ID
in "adb devices" (should be passed as "androidboot.serialno" to kernel
cmdline, via "bootargs" variable).

Serial number generating algorithm is described at [1].
