    rtc: pcf85063: fix potential OOB write in PCF85063 NVMEM read

    The nvmem interface supports variable buffer sizes, while the regmap
    interface operates with fixed-size storage. If an nvmem client uses a
    buffer size less than 4 bytes, regmap_read will write out of bounds
    as it expects the buffer to point at an unsigned int.

    Fix this by using an intermediary unsigned int to hold the value.
