Smatch complains because platform_get_resource() returns NULL on error
and not an error pointer so the check is wrong. Julia Lawall pointed
out that normally we don't check these, because devm_ioremap_resource()
has a check for NULL.

This patch adds NoC (Network on Chip) Probe driver which provides
the primitive values to get the performance data. The packets that the Network
on Chip (NoC) probes detects are transported over the network infrastructure.
Exynos542x bus has multiple NoC probes to provide bandwidth information about
behavior of the SoC that you can use while analyzing system performance.
