usb: dwc2_udc_otg: Add tx_fifo_sz array support
All TX fifo size can be different, add tx_fifo_sz_array[] into dwc2_plat_otg_data to be able to set them. tx_fifo_sz_array[] is 17 Bytes long and can contains max 16 tx fifo size (synopsys IP supports max 16 IN endpoints). First entry of tx_fifo_sz_array[] is the number of valid fifo size the array contains. In case of tx_fifo_sz_array[] doesn't contains the same number of element than max hardware endpoint, display a warning message. Compatibility with board which doesn't use tx_fifo_sz_array[] (Rockchip rk322x/rk3128/rv1108/rk3288/rk3036) is kept.
