remove dts
move changes from a64 hardware specific folders to rk3399
undo common changes (except head.s)
revert gitignore
missing irq.h and rk3399_serial.c need to finish cleaning them up

Adding the CONFIG_ARCH_PERF_EVENTS configuration to enable
hardware performance counting，solve the problem that some platform
hardware counting support is not perfect, you can choose to use
software interface.
This is configured using CONFIG_ARCH_PERF_EVENTS, so weak_functions
are removed to prevent confusion
To use hardware performance counting, must:
1. Configure CONFIG_ARCH_PERF_EVENTS, default selection
2. Call up_perf_init for initialization

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:

1. add lib_fork api in libs/libc, we need a fork() api to implement the
fork relative method, such as pthread_atfork
2. rename the assembly fork entry function name to up_fork(), and rename
the up_fork() to arch specific name, such as
sim_fork()/arm_fork()/mips_fork() etc.
