ARM: uniphier: add bootm_low environment 

The load address of the kernel can be changed via "kernel_addr_r"
environment.  The device tree and the initramdisk should be relocated
according to the kernel location.

The "bootm_low" should be calculated by masking the lower bits
(TEXT_OFFSET part) of the "kernel_addr_r" environment value.
