[PATCH 2/2] OMAP4: Kconfig: remove hotplug control for CPU0

On OMAP4, CPU0 cannot be dynamically offlined through the usual CPU
hotplug mechanism due to a variety of constraints.  It is treated as a
special "master" CPU for these reasons.

Select HOTPLUG_CPU_MASTER to prevent creation of the hotplug control
entry in sysfs.
