mmc: sdhci-brcmstb: Fix incorrect capability

Browse Source 
Clear incorrect SDHCI_CAN_64BIT capability on Broadcom MIPS based SoCs.
The MIPS based SoCs are using ADMA only, but the several SoCs have the
incorrect capability bit about ADMA 64-bit. The "brcm,bcm7425-sdhci" is
compatible string for MIPS based SoC.
