[U-Boot] [U-boot]: MMC: add sdhci generic framework

[Jagannadha Sutradharudu Teki]

Hi,

On..  drivers/mmc/sdhci.c
+       if (caps & SDHCI_CAN_DO_8BIT)
+               mmc->host_caps |= MMC_MODE_8BIT;

Here we are setting 8BIT bus width, if the sdhci capabilities register 18 bit is set.
Does 18-bit is really denoted for 8-bit bus width, I cound't find it on spec,  https://www.sdcard.org/developers/overview/host_controller/simple_spec/Simplified_SD_Host_Controller_Spec.pdf

Due to this above error even my controller doesn't support 8-bit, it shows a 8-BIT supported.

Request your help, correct me I am wrong.

Thanks,
Jagan.
