ENGR00178461-02 HDMI1080p: hotplug cause kernel panic. 10%
It is a warning cause by HDMI driver irq enable count mismatch.
The purpose of maintain HDMI irq count is to disable hdmi_iahb_clk
when HDMI cable plugout.
But hdmi_iahb_clk parent ahb clock is always enabled when system run,
so hdmi_iabh_clk power consumption is very low.
The function clk_get_usecount introduce by irq count maintain
is not safety in SMP.
Remove HDMI irq count in HDMI driver, keep hdmi_iahb_clk always run.
and disable hdmi_iahb_clk and hdmi_isfr_clk when FB Blank.
