Unlike kqueue/kevent of BSD, the epoll of Linux could be
add/del by using different API on the fly.
This patch drops the notify used by mevent_add/del and
call epoll_ctl to add/delete target fd. Only keeps
global_head to track mevent added and makes the code
logic in mevent_dispatch() a littel bit simpler.
Another thing is related with epoll_ctl. If the target
fd is regular fd which doesn't support epoll, epoll_ctl
will return -1. When DM is start by systemd, the STDIO
is not mapped to terminal, epoll_ctl on STDIO could
return -1. Which block UOS boot. We only call mevent_add
after confirm STDIO is mapped to terminal.

old code has no deinit functionality for virtual keyboard device.
Which will trigger resource leak when system is reboot.
deinit function is added to:
1. deinit low ps2 based keyboard and mouse
2. release memory/io resource of virtual keyboard device
NOTE: IRQ resource will be handed in pci irq module

Linux kernel CF9 reboot is doing things like:
- read value from 0xcf9
- mask out the value according to the reboot type (warm vs cold)
- BIT OR the value with reboot code
- write the value to 0xcf9
If there are two reboot event and the first one is cold
reboot and the second one is warm reboot, vsbl query
reboot type after the second one and will get code reboot
instead of warm reboot.
We should clear the data of 0xcf9 if guest request cold reboot.
