csky: Use va_pa_offset instead of phys_offset
The name of phys_offset is so common for global export and it may conflict with some local name. So change phys_offset to va_pa_offset which also used by riscv. Also use __pa() and __va() instead of using phys_offset directly. Signed-off-by: Guo Ren <ren_guo@c-sky.com> Cc: Arnd Bergmann <arnd@arndb.de>
