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.
