cpufreq: interactive: Use del_timer/add_timer_on to rearm timers

Replace mod_timer_pinned() with del_timer(), add_timer_on().
mod_timer_pinned() always adds timer onto current CPU. Interactive
governor expects each CPU's timers to be running on the same CPU.
If cpufreq_interactive_timer_resched() is called from another CPU,
the timer will be armed on the wrong CPU.

Replacing mod_timer_pinned() with del_timer() and add_timer_on()
guarantees timers are still run on the right CPU even if another
CPU reschedules the timer. This would provide more flexibility
for future changes.

If irq_enabled is set again, it causes the unblanced IRQ enable problem and

video: slimport: Set/clear sp_tx_pd_mode in the power control function

sp_tx_pd_mode is the flag if tx power is down or not. So it should be
controlled in the power control function.

video: slimport: Do not access the sp registers after power down

The burst i2c errors sometimes causes a watchdog reset. The i2c errors
are caused by accessing the sp registers after SP is power down. So
do not access the sp register after power down to avoid the watchdog reset.
