i2c: Delete outdated x1205 driver documentation
The x1205 driver moved to the RTC subsystem and was significantly modified since then, so just delete the outdated documentation. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Alessandro Zummo <alessandro.zummo@towertech.it>

14Description
15-----------
16
17This module aims to provide complete access to the Xicor X1205 RTC.
18Recently Xicor has merged with Intersil, but the chip is
19still sold under the Xicor brand.
20
21This chip is located at address 0x6f and uses a 2-byte register addressing.
22Two bytes need to be written to read a single register, while most
23other chips just require one and take the second one as the data
24to be written. To prevent corrupting unknown chips, the user must
25explicitely set the probe parameter.
26
27example:
28
29modprobe x1205 probe=0,0x6f
30
31The module supports one more option, hctosys, which is used to set the
32software clock from the x1205. On systems where the x1205 is the
33only hardware rtc, this parameter could be used to achieve a correct
34date/time earlier in the system boot sequence.
35
36example:
37
38modprobe x1205 probe=0,0x6f hctosys=1
