From: Micky Ching <micky_ch...@realsil.com.cn> Add support for sd/mmc async request, which makes next request do dma_map_sg() while previous request transfering data. This behaviour can improve card io performance more than 10%.
Since rtsx mfd driver only provide a single function for transfering data, so add three split functions for rtsx mmc driver.
