Add exports for __trace_hardirqs_on/_off and use them in
kernel/ex-entry.S and kernel/ex-exit.S to fix build/linker errors.
nds32le-linux-ld: arch/nds32/kernel/ex-entry.o: in function `fucop_ctl_done':
(.text+0x12a): undefined reference to `__trace_hardirqs_off'
(.text+0x12a): relocation truncated to fit: R_NDS32_25_PCREL_RELA against undefined symbol `__trace_hardirqs_off'
nds32le-linux-ld: arch/nds32/kernel/ex-exit.o: in function `no_work_pending':
(.text+0xea): undefined reference to `__trace_hardirqs_off'
nds32le-linux-ld: (.text+0xee): undefined reference to `__trace_hardirqs_off'
nds32le-linux-ld: (.text+0xf2): undefined reference to `__trace_hardirqs_on'
nds32le-linux-ld: (.text+0xf6): undefined reference to `__trace_hardirqs_on'
Fixes: 0cde56e0280d ("nds32: Fix a kernel panic issue because of wrong frame pointer access.")
