Shouldn't this be 'const void *of_fwnode_get_match_data

OF keeps the driver data as a (const void*) internally. ACPI keeps the
driver data as kernel_ulong_t in struct acpi_device_id.

I tried to find the middle ground here by converting output to void*
but not keeping const.

It should be no problem to cast a (const void *) to an unsigned long
data type (without const qualifier).
