This patch matches the input argument "size" of ioremap() with the output of request_mem_region() (which is
resource_size_t).
Since the latter is used as input to the former, the types should match (even though mapping more than 4G is not usually
expected). There are a lot of such differences in the code and this is an attempt to reduce that.
