    mvebu: fix RTC of IEI-World Puzzle M90x devices
    
    The Puzzle devices come with an I2C-connected Epson RX8130 RTC.
    Disable the (dysfunctional) RTC units of the SoC and add driver
    kmod-rtc-ds1307 to support the Epson RX8130 instead.

    (cherry picked from commit 6d546b3b4cdae3ffcdad71fb6cc414f3a39bc09e)
