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 0854/1085] dts: rp1: nobble HS and FS/LS park mode for dwc3
xhci
Synopsys have recommended that we disable this feature entirely, as
Superspeed park mode can hang the controller, and Hs/FS/LS park mode can
cause performance degradation with bursty devices.
