rtl8195am - move region headers to 0xb000 and 0xc000 

The new layout is as follows:

0x000000 - 0x008000  => bootloader
0x008000 - 0x00b000  => system sectors
0x00b000 - 0x00c000  => region1 header
0x00c000 - 0x00d000  => region2 header
0x00d000 - 0x010000  => reserved
0x010000 - 0x040000  => mbed file system
0x040000 - 0x120000  => region1 image
0x120000 - 0x200000  => region2 image

This is to ensure when daplink erases sections, both regions' headers
are erased properly.
