The length of some config elements are not equal to 1,2,4,8, so we can't
assert in virtio_mmio_config_read/write() direclty when length != 1,2,4,8
For example, in virtio_net_config from virtio spec v1.2
struct virtio_net_config {
u8 mac[6];
le16 status;
le16 max_virtqueue_pairs;
le16 mtu;
le32 speed;
u8 duplex;
u8 rss_max_key_size;
le16 rss_max_indirection_table_length;
le32 supported_hash_types;
};
The mac length is 6 and not equal to 1,2,4,8

Not found the mmio device is a normal case, so should not print the
error log.
This commit change the log level to info when not found the mmio

-The qemu wifi fucntion only supports the STA mode and the following
operations:
wapi mode wlan0 2
wapi scan wlan0
wapi psk wlan0 password 3
wapi essid wlan0 wifi_name 1
wapi show wlan0
wapi disconnect wlan0
-Eanble the virtual wifi function with the MACRO `CONFIG_DRIVERS_WIFI_SIM`.

Refers to https://docs.oasis-open.org/virtio/virtio/v1.2/cs01/virtio-v1.2-cs01.html#x1-2230004
A driver SHOULD negotiate VIRTIO_NET_F_MAC if the device offers it.
If the driver negotiates the VIRTIO_NET_F_MAC feature, the driver MUST
set the physical address of the NIC to mac. Otherwise, it SHOULD use a
locally-administered MAC address.

Openamp/libmetal's metal io operation used the atomic operation, but
in QEMU 8.1.2, the risc-v IO region is not allow to use atomic instruction
in SMP case.

The RPMB partition cannot be accessed via standard block layer, but by a set of specific commands: WRITE, READ, GET_WRITE_COUNTER, and PROGRAM_KEY. Such a partition provides authenticated and replay protected access, hence suitable as a secure storage.

TCP receive tested with different IOB_BUFSIZE:
| | 256B vs 1534B | 512B vs 1534B | 768B vs 1534B |
| :---------: | :-----------: | :-----------: | :-----------: |
| Non-SMP | ~85% | ~93% | ~96% |
| armv8a-SMP | ~66% | ~84% | ~92% |
| rv32/64-SMP | ~52% | ~72% | ~83% |
It seems we still get performance penalty on smaller IOBs, and may be
affected more under SMP mode. It may be caused by critical sections in
IOB operations.

Previously, the CONFIG_NET_LL_GUARDSIZE is fixed to 32 (64-Bit) or
28 (32-Bit), it's a little bit tricky.
Now add support to any value greater than minimal size.

1. virtio devics/drivers match and probe/remote mechanism;
2. virtio mmio transport layer based on OpenAmp (Compatible with both
virtio mmio version 1 and 2);
3. virtio-serial driver based on new virtio framework;
4. virtio-rng driver based on new virtio framework;
5. virtio-net driver based on new virtio framework
(IOB Offload implementation);
6. virtio-blk driver based on new virtio framework;
7. Remove the old virtio mmio framework, the old framework only
support mmio transport layer, and the new framwork support
more transport layer and this commit has implemented all the
old virtio drivers;
8. Refresh the the qemu-arm64 and qemu-riscv virtio related
configs, and update its README.txt;
New virtio-net driver has better performance
Compared with previous virtio-mmio-net:
