meson saradc: fix clock divider mask length
commit c57fa0037024c92c2ca34243e79e857da5d2c0a9 upstream.
According to the datasheets of supported meson SoCs length of ADC_CLK_DIV
field is 6-bit. Although all supported SoCs have the register
with that field documented later SoCs use external clock rather than
ADC internal clock so this patch affects only meson8 family (S8* SoCs).
