MIPS: octeon: Replace memset(0) + deprecated strcpy() with strscpy_pad()

Browse Source 
Replace memset(0) followed by the deprecated strcpy() with strscpy_pad()
to improve octeon_fdt_set_phy(). This avoids zeroing the memory before
copying the string and ensures the destination buffer is only written to
once, simplifying the code and improving efficiency.
