dlx: re-introduce PANEL_ID_DLX_SONY_RENESAS support

I added esc_byte_ratio = 2 for this panel, even though it wasn't
defined based on this code in the original HTC DLX kernel:

    #ifdef CONFIG_MSM_ALT_DSI_ESCAPE_CLOCK
          esc_byte_ratio = pinfo->mipi.esc_byt
    #else
          esc_byte_ratio = 2;
    #endif

Otherwise, it is a composite of the M7 Sony panel (for new fields
that have been added) and the panel that was in chad's kernel
based on the DLX source drop.
