arm64: Add macros to manage processor debug state
Add macros to enable and disable to manage PSTATE.D for debugging. The macros local_dbg_save and local_dbg_restore are moved to irqflags.h file KGDB boot tests fail because of PSTATE.D is masked. unmask it for debugging support Signed-off-by: Vijaya Kumar K <Vijaya.Kumar@caviumnetworks.com> Acked-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
