This commit is reported to cause UOS reboot fail becasue the
pci_businfo[] only be allocated when calling pci_parse_slot
in dm initialization while UOS reboot will not allocate again.
So we can't free it here.
This reverts commit 7aaff68798.

Current only 8 vioapic pins for pci irq (total 24 with 16 reserved),
which easily leads virtual GSI sharing with more and more passthrough
devices. This patch doulbes vioapic pin count and adds reboot hooks to
allocate from same pin after each reboot.

The current dm, all non-pci and non-acpi related files are put into
hw/platform directory. This is actually disturbed the meaning of
*platform*. The platform devices are mean of board and SoC specific
non-PCI devices, like usb devices, etc.
This patch refines the ACRN dm directory architecture.
For some common device logic files, likes block_if.c/uart_core.c or
usb_core.c. They will move to hw/ directly.
For platform architecture depended files, create arch/ under root dir.
And create sub-dir arch/x86 for x86 architecture, will create more
architectures in future. The pm.c will move to this new dir.
The hw/acpi will be moved to hw/platform/acpi due to acpi also be
considered as part of platform.

The original code assume there is only one configuration for
virtio-blk, and 'b' is just located after that configuration,
so to get the value of 'b', it will end char *config by adding
'\0' after the first configuration.
Thus, char *config will change from:
/XXXX_vdisk_file,range=xxx/xxx
to:
/XXXX_vdisk_file
and char *b will point to:
range=xxx/xxx
So, the range will never take effect for virtio-blk.
Now, 'b' is designed to located just after emul, and
char *config will point to all configurations after 'b'.
Note: only ",b," is taken for boot device option.

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.
