hwmon: (acpi_power_meter) Replace deprecated strcpy() with strscpy()

Browse Source 
strcpy() performs no bounds checking on the destination buffer, which
could result in linear overflows beyond the end of the buffer. Although
the source strings here are compile-time constants that fit within the
destination buffers, using strscpy() is the preferred approach as it
provides bounds checking and aligns with the kernel's deprecated API
guidelines.

This change converts the remaining strcpy() calls to strscpy(), matching
the pattern already used throughout other ACPI drivers in
drivers/acpi/*.c.
