ARM: Make target_phys_addr_t 64 bits and physaddrs 40 bits
Make target_phys_addr_t 64 bits for ARM targets, and set TARGET_PHYS_ADDR_SPACE_BITS to 40. This should have no effect for ARM boards where physical addresses really are 32 bits (except perhaps a slight performance hit on 32 bit hosts for system emulation) but allows us to implement the Large Physical Address Extensions for Cortex-A15, which mean 40 bit physical addresses.
