mfd: ti_am335x_tscadc: Mimic the probe from resume()
Use the number of touchscreen wires (tsc_wires) instead of the flag indicating a touchscreen cell (tsc_cell) to mimic the logic from the probe. Besides keeping a certain harmony in the driver, the main benefit is that we are going to simplify the number of entries in the main MFD structure and tsc_cell can now be removed more easily.
