Alexander Gordeev 7de0446f0b s390/boot: Make identity mapping base address explicit 
This is a preparatory rework to allow uncoupling virtual
and physical addresses spaces.

Currently the identity mapping base address is implicit
and is always set to zero. Make it explicit by putting
into __identity_base persistent boot variable and use it
in proper context - which is the value of PAGE_OFFSET.
