Pointers to struct qcom_icc_node (and similar structures) are not
modified, so they can be made const for safety. The contents of struct
qcom_icc_node must stay non-const.

To follow the example of the rest of icc-rpm.h drivers, expand
DEFINE_QNODE macros in the driver.

All icc-rpm drivers use the same set of bus clocks. Move handling of bus
clocks to qnoc_probe. This both simplifies the code and allows using
qnoc_probe as device's probe function.

The following errors are noticed during boot on a QCS404 board:
[ 2.926647] qcom_icc_rpm_smd_send mas 6 error -6
[ 2.934573] qcom_icc_rpm_smd_send mas 8 error -6
These errors show when we try to configure the GPU and display nodes.
Since these particular nodes aren't supported on RPM and are purely
local, we should just change their mas_rpm_id to -1 to avoid any
requests being sent for these master IDs.

Now we have a common function for standard aggregation, so let's use it,
instead of duplicating the code.

As we will remove items off the list using list_del(), we need to use the
safe version of list_for_each_entry().

This is a struct with a trailing zero-length array of icc_node pointers
but it's allocated as if it were a single array of icc_nodes instead.
This allocates too much memory at probe time but shouldn't have any
noticeable effect. Both sdm845 and qcs404 are affected.
Fix by replacing kcalloc with kzalloc and using the "struct_size" macro.

Add driver for the interconnect buses found in Qualcomm QCS404-based
platforms. The topology consists of three NoCs that are controlled by
a remote processor. This remote processor collects the aggregated
bandwidth for each master-slave pairs.
