V4L/DVB (13912): cx18: Fix tuner reset pin in card entry for the Leadtek PVR2100 



Fix the "xceive_pin" setting from "15" to "1" for the PVR2100 -- the same as
the PVR3100H.  This properly resets the XC2028 tuner on the PVR2100.

Sergey's original email report:

Hi.
Seems cx18 module has incorrect .xceive_pin value for card,
as i see lots of i2c errors in dmesg from xc2028.
i'm using 2.6.32.2, my hardware is:

00:09.0 Multimedia video controller [0400]: Conexant Systems, Inc. CX23418
Single-Chip MPEG-2 Encoder with Integrated Analog Video/Broadcast Audio Decoder

        Kernel driver in use: cx18

Following fixes this problem for me, the rest seems working:
