[ARM] pxa: use __raw_writel()/__raw_readl() for ssp_xxxx()
1. change SSP register definitions from absolute virtual addresses to offsets 2. use __raw_writel()/__raw_readl() for functions of ssp_xxxx() Signed-off-by: eric miao <eric.miao@marvell.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
