tscadc_readl and tscadc_writel are single line functions and do not save use anything, remove these.

All functions in this driver reference the same ti_tscadc_dev per device but use several different names for this structure pointer, this can be confusing when following the code. Use the name 'tscadc' everywhere.

The regmap structure pointer is named regmap_tscadc, this is not consistent with other drivers and is redundant, it also contributes to several checkpatch warnings involving long lines. Rename this.
