Fixes the following sparse warnings : line 504: warning: incorrect type in assignment (different base types) line 504: expected unsigned int [unsigned] [usertype] val line 504: got restricted __le32 [usertype] <noident> line 527: warning: cast to restricted __le32 This is solved by removing endian-converson functions, since the converted values are going through readl/writel anyway, which take care of the conversion.
