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 0950/1085] ARM: dts: bcm2712-rpi: Add i2c<n>_pins labels
Older Pi SoCs have friendly labels on the i2c pin nodes, e.g. i2c0_pins,
but they are absent from the BCM2712 dtsi files, even though UARTs and
SPI interfaces have them. Fix that omission.
