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 0879/1085] ASoC: DACplusADCPro - fix 16bit sample support in
clock consumer mode
The former code did not adjust the physical sample width when in
clock consumer mode and has taken the fixed 32 bit default. This
has caused the audio to be played at half its frequency due to
the fixed bclk_ratio of 64.
Problem appears only on PI5 as on the former PIs the I2S module
did simply run at fixed 64x rate.
