OMAP: DSS2: DSI: Introduce generic read functions
Introduce read functions which use generic Processor-to-Peripheral transaction types. These are needed by some devices which may not support corresponding DCS commands. Add function dsi_vc_generic_send_read_request() which can send a short packet with 0, 1 or 2 bytes of request data and the corresponding generic data type. Rename function dsi_vc_dcs_read_rx_fifo() to dsi_vc_read_rx_fifo() and modify it to take the enum "dss_dsi_content_type" as an argument to use either DCS or GENERIC Peripheral-to-Processor transaction types while parsing data read from the device.
