rename and "host" to "host_os_none" demo in prepare for creating host_freertos demo
create lpcxpresso project for host_freertos
adding host_freertos configure & build etc
getting build with freertos & host demo
rename nxp_sof_received to nxp_int_sof
implementing freeRTOS integration
change get_period_frame_list from using lst_idx to hostid (fix bug)
adding polling interval supported for interrupt: 1ms, 2ms, 4ms, 8ms
- add interval_ms to get_period_head function
- add bInterval to qhd_init
- add support for sub-frame (less than 8 micro frames) interval
- add bunch of test for interrupt different intervals
separate fake ehci's run async & period list
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
complete the support for correct polling of 1ms 2ms 4ms 8ms
change config to use USB0 only
fix some compiler warnings
