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 0694/1085] dt-bindings: PCI: brcmstb: add optional property -
"brcm,tperst-clk-ms"
This property can be used to delay deassertion of external fundamental
reset, which may be useful for endpoints that require an extended time for
internal setup to complete.
