arm64: dts: qcom: msm8996: Add device tree entries to support crypto engine
The change adds description of Qualcomm crypto engine controller and
BAM associated with it. The change is inspired by commit 3e482859f1ef
("dts: qcom: sdm845: Add dt entries to support crypto engine.")
While performance of cryptographic algorithms executed on QCE is lower
than e.g. ones tinkered for ARM NEON, the offloaded execution would
make sense:
# cryptsetup benchmark | grep aes
aes-cbc 128b 71.0 MiB/s 71.9 MiB/s
aes-cbc 256b 62.4 MiB/s 62.4 MiB/s
aes-xts 256b 70.7 MiB/s 70.8 MiB/s
aes-xts 512b 62.0 MiB/s 63.3 MiB/s
