[MIPS] Automatically set CONFIG_BUILD_ELF64

We do not rely on user anymore to setup this config correctly.
Instead we make our choice depending on the load address.

If we want to force Kbuild to use ELF64 format whatever
the load address we can still do:

        $ make BUILD_ELF32=no

-          A 64-bit kernel is usually built using the 64-bit ELF binary object
-          format as it's one that allows arbitrary 64-bit constructs.  For
-          kernels that are loaded within the KSEG compatibility segments the
-          32-bit ELF format can optionally be used resulting in a somewhat
-          smaller binary, but this option is not explicitly supported by the
-          toolchain and since binutils 2.14 it does not even work at all.
-
-          Say Y to use the 64-bit format or N to use the 32-bit one.

-          If unsure say Y.
