arch/csky patches for 4.21-rc1

Here is the arch/csky patch set for the 4.21-rc1 merge window.
Contianed in here is some features (cpu_hotplug, basic ftrace,
basic perf ...) and some bugfixes.

Features:
- Add CPU-hotplug support for SMP
- Add ftrace with function trace and function graph trace
- Add Perf support
- Add EM_CSKY_OLD 39
- optimize kernel panic print.
- remove syscall_exit_work

Bugfixes:
- fixup abiv2 mmap(... O_SYNC) failed.
- fixup gdb coredump error.
- fixup remove vdsp implement for kernel.
- fixup qemu fail to bootup sometimes.
- fixup ftrace call-graph panic
- fixup leak device tree node reference
- fixup remove meaningless header-y
- fixup save hi,lo,dspcr regs in switch_stack.
- fixup unused members in processor.h
