From: Stefano Stabellini <stefano.stabellini@xxxxxxx>
We introduce a new Kconfig CONFIG_SYSCTL, which shall only be disabled
on some dom0less systems or PV shim on x86, to reduce Xen footprint.
Making SYSCTL without prompt is transient and it will be adjusted in the final
patch. And the consequence of introducing "CONFIG_SYSCTL=y" in .config file
generated from pvshim_defconfig is transient too, which will also be adjusted
in the final patch.

v2 -> v3:
- remove "intend to" in commit message
---
v3 -> v4:
- introduce the option without prompt (simply "defbool y") to eliminate the
need for transient "#ifdef CONFIG_SYSCTL"
- calling out the transient scenario in commit message
---
v4 -> v5:
- a simple definition "def_bool y" for CONFIG_SYSCTL is enough here
- refactor commit message
- blank line ahead of endmenu
