separate fake ehci's run async & period list

Browse Source 
refractor list_find_previous_item & list_remove_qhd to act on ehci_link_t* instead of ehci_qhd_t*
fully support 1ms, 2ms, 4ms, 8ms for period list (each list has a dummy queue head)
- change period list structure
limit the maximum polling interval to 256 ms
add max_loop static MAX number of iteration for list_find_previous_item
add test for close 256ms polling interrupt
