Correctly handle USB_DESC_TYPE_OTHER_SPEED_CONFIGURATION request
in USB driver and support a different result than
USB_DESC_TYPE_CONFIGURATION with the new optional ops
get_other_speed_config_desc().
The support of this descriptor is optionnal and is only
required when high-speed capable device which can operate at its
other possible speed.
This patch allows to remove the pbuf update in usb_core_get_desc()
and solves an issue on USB re-enumeration on STM32MP15 platform
as the result of get_config_desc() is a const array.
This issue is not see on normal use-case, as the USB enumeration
is only done in ROM code and TF-A reuse the same USB descritors.

Since USBD_EP_NB = 1 for DFU stack on STMP32MP15 platform (only EP0 is
required for DFU support) the value of num can't be different of 0
and the code can't be reached in usb_core_receive / usb_core_transmit.
Add a simple sub-function with this part of code.

Add a new USB framework to manage an USB device profile (USBD)
based on a peripheral controller driver (PCD).
This USB stack can be use to implement any Universal Serial Bus Device
Class in TF-A on top of a USB driver defined in the platform.
