Reduce SD IO Voltage to 3.0Vpuma-release-4.4-2018-01-11-gopher
The SD-Card IO rail on the RK3399 should not be operated higher than 3.15V. We reduce it to 3.0V. Note that the I/Os on the Qseven edge connector will still be 3.3V as expected. Signed-off-by: Klaus Goger <klaus.goger@theobroma-systems.com>
