arch/csky patches for 5.3-rc1

This round of csky subsystem gives two features (ASID algorithm update,
Perf pmu record support) and some fixups.

Feature:
 - csky: Revert mmu ASID mechanism
 - csky: Add new asid lib code from arm
 - csky: Use generic asid algorithm to implement switch_mm
 - csky: Improve tlb operation with help of asid

 - csky: Init pmu as a device
 - csky: Add count-width property for csky pmu
 - csky: Add pmu interrupt support
 - csky: Fix perf record in kernel/user space
 - dt-bindings: csky: Add csky PMU bindings

Fixup:
 - csky: Fixup no panic in kernel for some traps
 - csky: Fixup some error count in 810 & 860.
 - csky: Fixup abiv1 memset error
