treewide: move CONFIG_PHYS_64BIT to Kconfig
We need to ensure that CONFIG_PHYS_64BIT is configured via Kconfig so that it is always available to the build system. Otherwise we can run into cases where we have inconsistent sizes of certain attributes. Ravi Babu reported offset mismatch of struct dwc3 across files since commit 95ebc253e6d4 ("types.h: move and redefine resource_size_t"). Since the commit, resource_addr_t points to phys_addr_t, whose size is dependent on CONFIG_PHYS_64BIT for ARM architecture. I tried my best to use "select" where possible (for example, ARMv8 architecture) because I think this kind of option is generally user- unconfigurable. However, I see some of PowerPC boards have 36BIT defconfigs as well as 32BIT ones. I moved CONFIG_PHYS_64BIT to the defconfigs for such boards. CONFIG_36BIT is no longer referenced, so all of the defines were removed from CONFIG_SYS_EXTRA_OPTIONS.
