When populating ACPI objects for floppy drives one needs to provide the maximum values for cylinder, sector, and head number the drive supports. This patch adds a function that iterates through the array of predefined floppy drive formats and returns the maximum values of c, h, s, out of those matching the given floppy drive type.
