1.disable host interrupts when id changed so that no more host
interrupt will happen after otg disconnect
2.hold hcd->lock in hcd_reinit function to protect qtd list
3.recheck USB_STATUS_ID in vbus detect thread make sure it indeed
in device mode
4.fix some null pointer dereference
5.otg disconnect threshold set to 575mv in case of disconnect
interrupt lose
Recover the code that remove in previous coding-style commit.
Without this code, hw could not running proberly.

1. Modify box display policy, rk_fb_update_reg() need to check yuv420
format.
2. When power up in uboot logo mode, if rk_fb_switch_screen input screen
type is not equal to current screen type, exit uboot logo mode. For
the case of display interface change happen at the moment of kernel
initialization.
3. Fox box, if RK_FBIOSET_YUV_ADDR input address is zero, we close related
lcdc layer. Because RK_FBIOSET_ENABLE may not be called by application,
especially at low memory enviorment,such as rk3036 256M ram.

Android generate Serial number too later than set 1 to
sys/class/android_usb/android0/enable. So here we have to manual
delay some time to enable usb connect in usb controler driver,
otherwise adb read a wrong serial number via usb then CTS test
will fail.

Disable iommu when decoding failure, so the iommu could
restore its state when the decoding resume.
Without this step, iommu will work in invalid state.

cpu0 is waiting for the other cpu respond ipi, but one cpu is blocked on getting &tasklist_lock
while irq is disabled and it will not respond ipi. If all the operation of &tasklist_lock is irq-disabled,
the &tasklist_lock will become available before the owner respond ipi, so the blocked cpu will get the
&tasklist_lock.
