irda: move drivers/net/irda to drivers/staging/irda/drivers

Move the irda drivers from drivers/net/irda/ to
drivers/staging/irda/drivers as they will be deleted in a future kernel
release.

-/*
- * This is my current (2007-04-25) understanding of how this dongle is supposed
- * to work. This is based on reverse-engineering and examination of the packet
- * data sent and received by the WinXP driver using USBSnoopy. Feel free to
- * update here as more of this dongle is known:
- *
- * General: Unlike the other USB IrDA dongles, this particular dongle exposes,
- * not two bulk (in and out) endpoints, but two *interrupt* ones. This dongle,
- * like the bulk based ones (stir4200.c and mcs7780.c), requires polling in
- * order to receive data.
- * Transmission: Just like stir4200, this dongle uses a raw stream of data,
- * which needs to be wrapped and escaped in a similar way as in stir4200.c.
- * Reception: Poll-based, as in stir4200. Each read returns the contents of a
- * 8-byte buffer, of which the first byte (LSB) indicates the number of bytes
- * (1-7) of valid data contained within the remaining 7 bytes. For example, if
- * the buffer had the following contents:
- *  06 ff ff ff c0 01 04 aa
- * This means that (06) there are 6 bytes of valid data. The byte 0xaa at the
- * end is garbage (left over from a previous reception) and is discarded.
- * If a read returns an "impossible" value as the length of valid data (such as
- * 0x36) in the first byte, then the buffer is uninitialized (as is the case of
- * first plug-in) and its contents should be discarded. There is currently no
- * evidence that the top 5 bits of the 1st byte of the buffer can have values
- * other than 0 once reception begins.
- * Once valid bytes are collected, the assembled stream is a sequence of
- * wrapped IrDA frames that is unwrapped and unescaped as in stir4200.c.
- * BIG FAT WARNING: the dongle does *not* reset the RX buffer in any way after
- * a successful read from the host, which means that in absence of further
- * reception, repeated reads from the dongle will return the exact same
- * contents repeatedly. Attempts to be smart and cache a previous read seem
- * to result in corrupted packets, so this driver depends on the unwrap logic
- * to sort out any repeated reads.
- * Speed change: no commands observed so far to change speed, assumed fixed
- * 9600bps (SIR).
