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 0933/1085] clk: rp1: Reserve pll_audio* for clk_i2s
Prevent all clocks except clk_i2s from using the audio PLLs as sources,
so that clk_i2s may be allowed to change them as needed.
