Use marco usb_memcpy and usb_memset for memcpy and memset

[kendryte747]

1. For my chip, use compiler libc memcpy in interrupt will crash, so use a marco of memcpy and memset to use custom function.
2. dwc2 default enable use dma, but seems my chip's usb controller not support it, so change this marco logic.

Its your libc issue not mine, so you need implment your libc

memcpy is a standard api, must be implmented.

dma is for hs port ,iif you do not support , please use fs port.

so i need custom the memcpy used by cherryusb.

I want to control dma support in usb_config.h, but here it is defined directly

You can enable fs port, not hs port, it is the same.

[sakumisu]

CONFIG_USB_DWC2_DMA_ENABLE only uses in hs port.

memcpy is the common api not only in cherryusb, but also in almost other opensource projects.

ok...
