drivers/rtc/Kconfig: disable RTC_DRV_CMOS on Atari

Browse Source 
On ARAnyM (emulating an Atari Falcon, which doesn't have an RTC IRQ, as
the Second Multi Function Peripheral MFP 68901 is available on Atari TT
only), rtc-cmos doesn't work well:

  - The date is of by 32 years (2045 instead of 2013):

    rtc_cmos rtc_cmos: setting system clock to 2045-12-02 10:56:17 UTC
    (2395824977)

  - The hwclock utility doesn't work:

    hwclock: ioctl() to /dev/rtc to turn on update interrupts failed
    unexpectedly, errno=5: Input/output error.

As rtc-generic works fine for the RTC part, and nvram works for the NVRAM
part, we'll continue on using that.
