Revert "ARM: dts: bcm2711: Add the BSC interrupt controller"

raspberrypi inclusion
category: feature
bugzilla: 50432

--------------------------------

This reverts commit 93a3b097c467bd5efc1ae3a271c336fdad3b2108.

GIC interrupt 117 is shared with the HDMI interrupt controller
and all the standard BSC I2C controllers. Whilst the BSC driver
flags the interrupt as shared, there doesn't appear to be an
easy way to flag the controller as being on a shared parent
interrupt.

Revert to polling the I2C controllers.
