Merge tag 'qcom-drivers-for-6.4-2' of https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux into soc/drivers

A few more Qualcomm driver updates for v6.4

This introduces a new binding and a dedicated driver for the Qualcomm
Inline-Crypto-Engine (ICE), in order to support a single shared instance
between SDHCI and UFS, found in recent platforms.

RSC version check is updated to support minor revisions of v3 of the ip
block, the SMD-RPM interface is transitioned to GFP_ATOMIC to avoid the
shrinker to kick in underneath the GPU and QCM2290 support is added to
the SCM binding.
