 * The USB device global variables are put into the section m_usb_global and m_usb_bdt or the section
 * .bss.m_usb_global and .bss.m_usb_bdt by using the MACRO USB_GLOBAL and USB_BDT. In this way, the USB device
 * global variables can be linked into USB dedicated RAM by USB_STACK_USE_DEDICATED_RAM.
 * The MACRO USB_STACK_USE_DEDICATED_RAM is used to decide the USB stack uses dedicated RAM or not. The value of
 * the marco can be set as 0, USB_STACK_DEDICATED_RAM_TYPE_BDT_GLOBAL, or USB_STACK_DEDICATED_RAM_TYPE_BDT.
 * The MACRO USB_STACK_DEDICATED_RAM_TYPE_BDT_GLOBAL means USB device global variables, including USB_BDT and
 * USB_GLOBAL, are put into the USB dedicated RAM. This feature can only be enabled when the USB dedicated RAM
 * is not less than 2K Bytes.
 * The MACRO USB_STACK_DEDICATED_RAM_TYPE_BDT means USB device global variables, only including USB_BDT, are put
 * into the USB dedicated RAM, the USB_GLOBAL will be put into .bss section. This feature is used for some SOCs,
 * the USB dedicated RAM size is not more than 512 Bytes.
