libpayload: Cache physical cbmem console address

Same as with other consoles and drivers that cache an address
outside the payload (e.g. video/corebootfb), we should store the
physical address, so we can derive the virtual address on demand.
This makes it save to use the address across relocations.

As a first step in migrating `libsysinfo` to `uintptr_t`, we
also switch to the physical address there.

Fixes the default build of FILO, tested with Qemu/i440FX and Qemu/Q35.
