ntb: intel: constify ioreadX() iomem argument (as in generic implementation)
...
The ioreadX() helpers have inconsistent interface. On some architectures
void *__iomem address argument is a pointer to const, on some not.
Implementations of ioreadX() do not modify the memory under the address so
they can be converted to a "const" version for const-safety and
consistency among architectures.

ntb: intel: Add Icelake (gen4) support for Intel NTB
...
Adding 4th generation Intel NTB support bits. There are a lot of common
parts that the gen4 NTB has with gen3 NTB on Skylake. The commonalities are
reused in gen4 Icelake NTB.

ntb: intel: split out the gen3 code
...
Move the Intel hw gen3 code to its own source file. The ntb_hw_intel.c was
getting too large and makes it hard to maintain with future hardware
changes.
