Why not this:

const struct of_device_id hidma_msi_of_ids[] = {
	{.compatible = "qcom,hidma-1.1",},
	{.compatible = "qcom,hidma-1.2",},
	{},
},

static const struct acpi_device_id hidma_msi_acpi_ids[] = {
	{"QCOM8001", QDF2XXX_V1},
	{"QCOM8002", QDF2XXX_V2},
	{},
};

struct hidma_cap {
	const struct of_device_id *of;
	const struct acpi_device_id *acpi;
};

static struct hidma_cap hidma_msi_cap = {
	hidma_msi_of_ids,
	hidma_msi_acpi_ids
}

Keep in mind that you also need to add MODULE_DEVICE_TABLE entries, 
which you can't really do with your approach.

MODULE_DEVICE_TABLE(of, hidma_msi_of_ids);
MODULE_DEVICE_TABLE(acpi, hidma_msi_acpi_ids);
