This takes care of 2 TODOs in this driver, by using the common DSI packet-marshalling code instead of our custom short/long write code. This both saves us some duplicated code and gets us free support for command types that weren't already part of our switch block (e.g., MIPI_DSI_GENERIC_LONG_WRITE). The code logic stays mostly intact, except that it becomes unnecessary to split the short/long write functions, and we have to copy data a bit more. Along the way, I noticed that loop bounds were a little odd: while (DIV_ROUND_UP(len, pld_data_bytes)) This really was just supposed to be 'len != 0', so I made that more clear. Tested on RK3399 with some pending refactoring patches by Nickey Yang, to make the Rockchip DSI driver wrap this common driver.
