USB: aten uc2324 is really a moschip 7840

I've opened up the case, and the chips in the ATEN UC2324 are:

Moschip
MCS7840CV-AA
69507-6B1
0650
(USB to 4-port serial)

(logo with AF kerned together)  0748  
24BC02  
SINGLP
(unknown 8-pin chip)

(logo looks like 3 or Z in circle)
ZT3243LEEA    0752
B7A16420.T
(4 chips, so this will be RS232 line driver)
(Probably equivalent of Sipex SP3243)

So the ATEN 2324 (aten2011.c driver), is definitely the Moschip 7840,
and should use the mos7840.c driver.  I expect you will remove the
aten2011.c driver from the staging area.

From the aten2011.c source code, the device ID for the UC2322 (2 port
serial) is 0x7820, just like the Moschip evaluation board.  This value
should be added to the device id table of mos7840.c.

Here's a patch that adds these devices to the driver.
