msm-nand: Enable interleave mode based on modem build ID.

Browse source 
Add build id detection to enable the interleave mode feature in the driver.
In the interleave mode image ( boot, userdata etc ) codewords are written
to the NAND devices in a interleave fashion. Hence modem and apps should
operate in the same mode to read/write the images properly.
