MIPS: Make the default for PHYSICAL_START always 64-bit
Make the default for PHYSICAL_START always 64-bit, ensuring that a correct sign-extended value is used if a 32-bit image is loaded by a 64-bit system, and matching how the load address is set in platform Makefile fragments (arch/mips/*/Platform) in the absence of the PHYSICAL_START configuration option. Of course PHYSICAL_START itself is a misnomer as the load address is virtual rather than physical (or otherwise sign-extension would not apply).

This gives the CKSEG0 or KSEG0 address where the kernel is loaded.
