MFD: ti_tscadc: ADC Clock check not required
ADC is ideally expected to work at a frequency of 3MHz. The present code had a check, which returned error if the frequency went below the threshold value. But since AM335x supports various working frequencies, this check is not required. Now the code just uses the internal ADC clock divider to set the ADC frequency w.r.t the sys clock.
