rk3399-puma.dts: reduce eMMC freq to 100MHz
Running at the default frequency of 200MHz, CRC errors (error -84 = EILSEQ) have been observed on three boards. Reduce the freqency to 100MHz to fix the issue on the affected boards and for safety on all others. Signed-off-by: Jakob Unterwurzacher <jakob.unterwurzacher@theobroma-systems.com>
