In the SDHCI specification, the Capabilities Register (Offset 0x40h) is the 64-bit width register, but in Linux, it is represented as two registers, SDHCI_CAPABILITIES and SDHCI_CAPABILITIES_1 so that drivers can use 32-bit register accessors.
The upper 32-bit field is associated with SDHCI_CAPABILITIES_1.
Move the definition of SDHCI_CAPABILITIES_1 to the correct place.
