Revert "ARM: 7587/1: implement optimized percpu variable access"

This reverts commit 859174f630d8dff3a2cb5991ab82f6146069351a.
Switch MSM HOTPLUG ,INTELLI HOTPLUG, CPU LIMIT to LCD_NOTIFY wakeup.

Also fix miss define in case that LCD_NOTIFY is used.
HOTPUGS: Fixed CRITICAL error!!! Suspend was NOT working! now OK.

Hotplugs never suspended! as min suspend cores was se to 2!

This wasted power!

*Also i have added faster LCD notification in mdss_dsi_panel
so it's hotplugs will resume with mdss_dsi_panel_on

Also allowed cpu-boost/cpufreq_limit to use LCD_NOTIFY
