soc: qcom: llcc: update to v5.19-rc6

Backport Qualcomm LLCC support. This will be enabled as the need arises (e.g,
automotive SA8540P uses the same driver as SC8280XP).

Bugzilla: https://bugzilla.redhat.com/2108329
Tested: Sanity boot on qti-snapdragon-02-sip2 with CONFIG_QCOM_LLCC=m, module loaded/probed successfuly.
