ARC's asm/io.h includes the asm-generic/io.h which already defines the
PCI_IOBASE variable in exactly the same way, so it can be dropped from
the architecture specific header.

Some drivers require these, and ARC didn't had them yet.

Implement ioremap_prot() to allow mapping IO memory with variable
protection
via TLB.
Implementing this allows the /dev/mem driver to use its generic access()
VMA callback, which in turn allows ptrace to examine data in memory
mapped regions mapped via /dev/mem, such as Arc DCCM.
The end result is that it is possible to examine values of variables
placed into DCCM in user space programs via GDB.
