staging: rts5208: add support for rts5208 and rts5288
There are still many rts5208/5288 card readers being used, but no drivers are supported them in kernel now. This driver can make a great convenience for people who use them. Many other rts-series card reader are supported by mfd driver, but due to much difference with others, rts5208/5288 can not add into mfd driver pretty now, so we provide a separated driver here to support the device.
