Christoph Muellner b4e1728232 arm64: dts: rockchip: Decrease emmc-phy's drive impedance on rk3399-puma 
The RK3399-Q7 (Puma) requires 33 Ohm drive strength to ensure signal
integrity at HS-400 (200MHz clock, DDR signalling).

A repeated EMC testing run validates that this increase does not
negatively impact EMC compliance (emissions have ample distance to
the regulatory limits).
