[PATCH v10 3/3] ARM: uncompress: Validate start of physical memory against passed DTB

Currently, the start address of physical memory is obtained by masking the program counter with a fixed mask of 0xf800. This mask value was chosen as a balance between the requirements of different platforms. However, this does require that the start address of physical memory is a multiple
