PD#146713: configurate DMA of HDCP correctly
1.In kernel 4.9, before DMA operation, of_dma_configure function must
be used. Otherwise, it will get a NULL pointer and result in a kernel
crash.
2.For secure reasons, node '/dev/mem' has gone away. But for esm, there
still need this feature for debug. So add a new blob for esay dump:
dd if=/sys/kernel/debug/esm/blob of=/UPATH/esmmem.

PD#148057: for m8bb m200 platform, we have the latest linux kernel
and a relative old version uboot running on it. For some historic
resons, the unifykey data stored in emmc/nand has totally different
format, which means the key stored by old uboot cannot be fetched
out by new kernel. To solve this problem, we have to support both
the old and new unifykey dataformat in lasted kernel.
