kaktus 499b2b5652 Mark more nodes as CTLFLAG_MPSAFE or CTLFLAG_NEEDGIANT (2 of many) 
r357614 added CTLFLAG_NEEDGIANT to make it easier to find nodes that are
still not MPSAFE (or already are but aren’t properly marked). Use it in
preparation for a general review of all nodes.
This is non-functional change that adds annotations to SYSCTL_NODE and
SYSCTL_PROC nodes using one of the soon-to-be-required flags.

* IO buffer sizes and FTDI device procotol sizes.
*
* Note that the output packet size in the following defines is not the usb
* protocol packet size based on bus speed, it is the size dictated by the FTDI
* device itself, and is used only on older chips.
*
* We allocate buffers bigger than the hardware's packet size, and process
* multiple packets within each buffer. This allows the controller to make
* optimal use of the usb bus by conducting multiple transfers with the device
* during a single bus timeslice to fill or drain the chip's fifos.
*
* The output data on newer chips has no packet header, and we are able to pack
* any number of output bytes into a buffer. On some older chips, each output
* packet contains a 1-byte header and up to 63 bytes of payload. The size is
* encoded in 6 bits of the header, hence the 64-byte limit on packet size. We
* loop to fill the buffer with many of these header+payload packets.
*
* The input data on all chips consists of packets which contain a 2-byte header
* followed by data payload. The total size of the packet is wMaxPacketSize
* which can change based on the bus speed (e.g., 64 for full speed, 512 for
* high speed). We loop to extract the headers and payloads from the packets
* packed into an input buffer.
