[stable for 3.2][patch] Kernel 3.2 add support for IT9135 chip version 2 devices.

[Malcolm Priestley <tvboxspy@gmail.com>]

Originally, IT9135 chip version 2 devices were never intended to be supported in kernel 3.2
as they were thought at the time only on ID 048d:9006.

However, they have since been supplied on ID 048d:9135, the following error occurs.

[   53.512013] usb 2-4: new high-speed USB device number 5 using ehci_hcd
[   53.648936] it913x: Chip Version=02 Chip Type=9135

[   55.188050] it913x: DEV it913x Error


This patch and the cherry picks fixes the issue and applies firmware differences
in commit 7330f7c157308166c507da9b9926107d85f960d3 and the 3.2 tree.

The driver is updated to version it913x 1.24 and it913x-fe 1.12.

Note existing 048d:9135 version 1 users will need to switch to dvb-usb-it9135-01.fw
firmware as in kernel 3.3 after this update.

./get_dvb_firmware it9135
extracts
dvb-usb-it9135-01.fw
dvb-usb-it9135-02.fw

./get_dvb_firmware it9137
extracts
dvb-usb-it9137-01.fw

The following upstream cherry-picks in order need to be applied.
