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 0269/1085] PCI: brcmstb: Advertise MSI-X support
+
+Although the BRCMSTB PCIe interface doesn't technically support the
+MSI-X spec, in practise it seems to work provided no more than 32
+MSI-Xs are required. Add the required flag to the driver to allow
+experimentation with devices that demand MSI-X support.
