/**
 * TouchGFX generic initialize.
 *
 * @tparam HALType The class type of the HAL subclass used for this port.
 * @param [in] dma                    Reference to the DMA implementation object to use. Can be of
 *                                    type NoDMA to disable the use of DMA for rendering.
 * @param [in] display                Reference to the LCD renderer implementation (subclass of
 *                                    LCD). Could be either LCD16bpp for RGB565 UIs, or
 *                                    LCD1bpp for monochrome UIs or LCD24bpp for 24bit
 *                                    displays using RGB888 UIs.
 * @param [in] tc                     Reference to the touch controller driver (or
 *                                    NoTouchController to disable touch input).
 * @param      width                  The \a native display width of the actual display, in pixels.
 *                                    This value is irrespective of whether the concrete UI
 *                                    should be portrait or landscape mode. It must match
 *                                    what the display itself is configured as.
 * @param      height                 The \a native display height of the actual display, in
 *                                    pixels. This value is irrespective of whether the
 *                                    concrete UI should be portrait or landscape mode. It
 *                                    must match what the display itself is configured as.
 * @param [in] bitmapCache            Optional pointer to starting address of a memory region in
 *                                    which to place the bitmap cache. Usually in external
 *                                    RAM. Pass 0 if bitmap caching is not used.
 * @param      bitmapCacheSize        Size of bitmap cache in bytes. Pass 0 if bitmap cache is not
 *                                    used.
 * @param      numberOfDynamicBitmaps (Optional) Number of dynamic bitmaps.
 *
 * @return A reference to the allocated (and initialized) HAL object.
