[PATCH] MMC: wbsd update

Updates to the wbsd driver.
                                                                                
* Fix to handle DAT3 card detection.
* Fixed bug which could cause large writes to stall in FIFO mode.
* Plug 'n Play support. In most cases you need ACPI PNP for this to work.
* Uses generic DMA API (ISA dependency removed).
