[PATCH 2/3] genirq: Remove unused irq_chip_generic::{type,polarity}_cache

["Jiri Slaby (SUSE)" <jirislaby@kernel.org>]

The type_cache and polarity_cache members of struct irq_chip_generic are
unused. Remove them both along with their kernel-doc.

Found by https://github.com/jirislaby/clang-struct.
