usb serial: support Alcor Micro Corp. USB 2.0 TO RS-232 through pl2303 driver

Patch to add support for Alcor Micro Corp. USB 2.0 TO RS-232 converter.
This patch adds VID and PID to pl2303.[ch], adds it to the "HORRIBLE
HACK FOR PL2303" in usb-serial.c and also prevents cdc-acm to claim
driving this device by blacklisting it in hid-core.
