[PATCH 03/10] dts: aspeed: ast2600: Support SDR50 for SD device

[Chin-Ting Kuo]

The maximum frequency for SD controller on AST2600 EVB is
100MHz. In order to achieve 100MHz, sd-uhs-sdr50 property
should be added and the driver will set the SDR50 supported
bit in capability 2 register during probing stage.
