asm-generic: provide phys_to_virt() and virt_to_phys()
The arm, riscv, sandbox and x86 architectures use
just the same phys_to_virt()/virt_to_phys() implementation.
Only the mips architecture has its own special implementation.
So we can move phys_to_virt() and virt_to_phys()
generic implementation to include/asm-generic/io.h.
Use override functions way introduced in the 9216efafc52ff99e
("asm-generic/io.h: Reconcile I/O accessor overrides")
linux kernel commit.
