The definition of MSR_MISC_FEATURE_CONTROL was first introduced in
98af74599ea0 ("x86 msr_index.h: Define MSR_MISC_FEATURE_CONTROL")
and present in Linux since v4.11.
The Cache Pseudo-Locking code added this duplicate definition in more
recent
f2a177292bd0 ("x86/intel_rdt: Discover supported platforms via prefetch disable bits"),
available since v4.19.
Remove the duplicate definition from the resctrl subsystem and let that
code obtain the needed definition from the core architecture msr-index.h
instead.
Fixes: f2a177292bd0 ("x86/intel_rdt: Discover supported platforms via prefetch disable bits")

Fix the messages in rdt_last_cmd_printf() and rdt_last_cmd_puts() to
make them more meaningful and consistent.

New generation of AMD processors add support for RDT (or QOS) features.
Together, these features will be called RESCTRL. With more than one
vendors supporting these features, it seems more appropriate to rename
these files.
Create a new directory with the name 'resctrl' and move all the
intel_rdt files to the new directory. This way all the resctrl related
code resides inside one directory.
