V4L/DVB (5373): [PATCH] Hauppauge Nova-T endianess problem on powerpc

When trying to use a Hauppauge Nova-T Stick on a big-endian architecture
(such as powerpc) no frontend can be attached.
The attached patch fixes this problem by removing two lines in
dib0700_ctrl_rd() that try to correct the endianess on two values that
already are correct:
-       /* think about swapping here */
-       value = le16_to_cpu(value);
-       index = le16_to_cpu(index);
With this simple patch this dvb hardware works great, thanks to anyone
involved for the good work. :)
