[PATCH v2 27/27] mfd: ti_am335x_tscadc: Remove redundant ti_tscadc_dev_get() helper

[Lee Jones <lee@kernel.org>]

Now that ti_tscadc_dev_get() is a single-line wrapper around
dev_get_drvdata(p->dev.parent), remove the bespoke helper and retrieve
the parent driver data directly in the child ADC and touchscreen
drivers.
