fix(drivers/usb): add a optional ops get_other_speed_config_desc

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.
