power: reset: at91: Drop '__init' from at91_wakeup_status()

When building with clang, there are two section mismatch warnings:

  WARNING: modpost: vmlinux: section mismatch in reference: at91_poweroff_probe+0x7c (section: .text) -> at91_wakeup_status (section: .init.text)
  WARNING: modpost: vmlinux: section mismatch in reference: at91_shdwc_probe+0xcc (section: .text) -> at91_wakeup_status (section: .init.text)

Drop '__init' from at91_wakeup_status() to clear up the mismatch.

Fixes: dde74a5de817 ("power: reset: at91-sama5d2_shdwc: Stop using module_platform_driver_probe()")
Fixes: 099806de68b7 ("power: reset: at91-poweroff: Stop using module_platform_driver_probe()")

I suspect this is not visible for GCC due to inlining
at91_wakeup_status() but I did not actually check.

Best regards,

Ping? I still see these warnings in next-20231205.
