[media] saa7115: Fix standards detection
There are several bugs at saa7115 standards detection:
After the fix, the driver is returning the proper standards,
as tested with 3 different broadcast sources:
On an invalid channel (without any TV signal):
[ 4394.931630] saa7115 15-0021: Status byte 2 (0x1f)=0xe0
[ 4394.931635] saa7115 15-0021: detected std mask = 00ffffff
With a PAL/M signal:
[ 4410.836855] saa7115 15-0021: Status byte 2 (0x1f)=0xb1
[ 4410.837727] saa7115 15-0021: Status byte 1 (0x1e)=0x82
[ 4410.837731] saa7115 15-0021: detected std mask = 00000900
With a NTSC/M signal:
[ 4422.383893] saa7115 15-0021: Status byte 2 (0x1f)=0xb1
[ 4422.384768] saa7115 15-0021: Status byte 1 (0x1e)=0x81
[ 4422.384772] saa7115 15-0021: detected std mask = 0000b000
Tests were done with a WinTV PVR USB2 Model 29xx card.
