* system/smp: Add LoongArch SMP support

Added LoongArch multi-core support and a way of map to node numbers if
the NUMA is enabled.

Signed-off-by: Chao Li <lichao@loongson.cn>

* system/timers: Add LoongArch supports

In LoongArch, there is a stable counter that is independent of other
clocks, it like the TSC in x64. Using it to count the ticks per
millisecond.

Signed-off-by: Chao Li <lichao@loongson.cn>

* system/tsc: Add LoongArch support

Usually the frequency of stable counter is not same to CPU frequency, so
using the performance counter for the delay operations.

* system/usbhcd: Add Loongson 7A2000 chipset OHCI BAR offset fix

If the BAR address is not fixed for the Loongson 7A2000 OHCI controller,
some prots will not be usable, This change currently only affects the
LoongArch platform.

* system: Add the way to IO access via MMIO

Usually, it is access the IO like PCI IO via MMIO on non-X86 ARCHs, so
a method to access IO via MMIO is added.

Signed-off-by: Chao Li <lichao@loongson.cn>

* system: Add the way to access PCI memory space via MMIO

Some uniformly address ARCHs access the PCI memory depended the MMIO, so
the method to access PCI memory via MMIO is added.
