board: t208x: Extend cs4340_get_fw_addr() functionality

T2080RDB supports booting from 2 nor banks(default and altbank). The
corresponding defconfig can only have one entry defined and therefore,
extend cs4340_get_fw_addr() function to overwrite firmware address which
will be later used in cortina firmware.
