Add missing Broadcast_AND region to the LLCC block for x1e80100,
as the LLCC version on this platform is 4.1 and it provides the region.
This also fixes the following error caused by the missing region:
[ 3.797768] qcom-llcc 25000000.system-cache-controller: error -EINVAL: invalid resource (null)
This error started showing up only after the new regmap region called
Broadcast_AND that has been added to the llcc-qcom driver.
Cc: stable@xxxxxxxxxxxxxxx # 6.11: 055afc34fd21: soc: qcom: llcc: Add regmap for Broadcast_AND region
Fixes: af16b00578a7 ("arm64: dts: qcom: Add base X1E80100 dtsi and the QCP dts")

- fixed subject line to say x1e80100 instead of sm8450
- mentioned the reason why the new error is showing up
and how it is related to the llcc-qcom driver
- cc'ed stable with patch dependency for cherry-picking
- Link to v1: https://lore.kernel.org/r/20240718-x1e80100-dts-llcc-add-broadcastand_region-v1-1-20b6edf4557e@xxxxxxxxxx
