dm: Fix OF_BAD_ADDR definition
When OF_LIVE flag is enabled on a 64 bits platform, there is an
issue when dev_read_addr() is called and need to perform an address
translation using __of_translate_address().
In case of error, __of_translate_address() return's value is OF_BAD_ADDR
(wich is defined in include/dm/of.h to ((u64)-1) = 0xffffffffffffffff).
The return value of dev_read_addr() is often compared to FDT_ADDR_T_NONE
which is defined as (-1U) = 0xffffffff.
In this case the comparison is always false.
To fix this issue, define FDT_ADDR_T_NONE to (ulong)(-1) in case of
AARCH64. Update accordingly related tests.
