[SPARC]: iomem annotations in SOC driver

	* struct soc_cq split into two variants differing only in annotations -
ones we use for requests have ->pool pointing to normal memory, ones for
responses have it pointing to iomem.
	* all instances of soc_cq were either always of request or always of
response variety; replaced with soc_cq_rsp and soc_cq_req resp.
	* the rest consists of trivial adding __iomem where needed - the
only tricky bit had been soc_cq annotations.
