media: ddbridge/mci: add SX8 I/Q mode remark and remove DIAG CMD defines

#define SX8_TSCONFIG_MODE_NORMAL            (0x00000001)

#define SX8_TSCONFIG_MODE_IQ                (0x00000003)

/*

 * IQMode is only available on MaxSX8 on a single tuner

 *

 * IQ_MODE_SAMPLES

 *       sampling rate is 1550/24 MHz (64.583 MHz)

 *       channel agc is frozen, to allow stitching the FFT results together

 *

 * IQ_MODE_VTM

 *       sampling rate is the supplied symbolrate

 *       channel agc is active

 *

 * in both cases down sampling is done with a RRC Filter (currently fixed to

 * alpha = 0.05) which causes some (ca 5%) aliasing at the edges from

 * outside the spectrum
