[PATCH v8 09/11] i386/pc: bounds check phys-bits against max used GPA

Calculate max *used* GPA against the CPU maximum possible address and error out if the former surprasses the latter. This ensures max used GPA is reacheable by configured phys-bits. Default phys-bits on Qemu is TCG_PHYS_ADDR_BITS (40) which is enough for the CPU to address 1Tb (0xff ) or 1
