Álvaro Fernández Rojas 8c405cdccc bcm27xx: add 6.6 kernel patches
The patches were generated from the RPi repo with the following command:
git format-patch v6.6.34..rpi-6.1.y

Some patches needed rebasing and, as usual, the applied and reverted, wireless
drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0117/1085] ARM: Activate FIQs to avoid __irq_startup warnings
There is a new test in __irq_startup that the IRQ is activated, which
hasn't been the case for FIQs since they bypass some of the usual setup.
Augment enable_fiq to include a call to irq_activate to avoid the
warning.
