[PATCH] sonypi: use strscpy() in sonypi_acpi_probe

[Thorsten Blum]

strcpy() has been deprecated¹ because it performs no bounds checking on
the destination buffer, which can lead to buffer overflows. While the
current code works correctly, replace strcpy() with the safer strscpy()
to follow secure coding best practices.
