Geert Uytterhoeven 27d632d27c m68k/atari: Hide RTC_PORT() macro from rtc-cmos
Rename RTC_PORT() to ATARI_RTC_PORT(), as the rtc-cmos RTC driver uses the
presence of this macro to enable support for the second NVRAM bank, which
Atari doesn't have ("Unable to handle kernel access at virtual address
00ff8965").
