Windows on UEFI systems is only capable of detecting the presence and the type of floppy drives via corresponding ACPI objects.
Those objects are added in the last patch of the series; the three preceding ones pave the way to it, by making the necessary data public and by moving the whole floppy drive controller description into runtime-generated SSDT. Note that the series conflicts with Igor's patchset for dynamic DSDT, in particular, with "[PATCH 50/74] pc: acpi: move FDC0 device from DSDT to SSDT"; I haven't managed to avoid that while trying to meet maintainer's comments.
