Do you mean that I should use #ifdef CONFIG_ACPI and ACPI_PTR?

#ifdef CONFIG_ACPI
static const struct acpi_device_id goodix_acpi_match[] = {
	{ "GDIX1001", 0 },
	{ }
};
MODULE_DEVICE_TABLE(acpi, goodix_acpi_match);
#endif

#ifdef CONFIG_OF
static struct of_device_id goodix_of_match[] = {
	{ .compatible = "goodix,gt9xx" },
	{ }
};
MODULE_DEVICE_TABLE(of, goodix_of_match);
#endif

static struct i2c_driver goodix_ts_driver = {
	...
		.acpi_match_table = ACPI_PTR(goodix_acpi_match),
		.of_match_table = of_match_ptr(goodix_of_match),
}

Look at include/linux/of.h

#ifdef CONFIG_OF
 ...
#define of_match_ptr(_ptr)	(_ptr)
 ...
#else /* CONFIG_OF */
 ...
#define of_match_ptr(_ptr)	NULL
 ...
#endif /* CONFIG_OF */

So it would be compiled. Similarly in other touchscreen drivers.
But Kconfig should be fixed to enable CONFIG_OF. Will be fixed in v2.

I was thinking, instead of depending on (ACPI || OF), can we make ACPI
optional as well and remove the dependency on it?
Does it make sense to allow selecting a driver even with no
enabled mechanism to pass platform data to it?

Thanks,
