sdmmc: Refactor again

Browse Source 
- Refactor various variables and defines
- Removed Card/BGA and OEM ID info as they are static and useless
- Commented out bkops functions completely as not used
- Remove extra buf usage when there's already storage for storing that data
- Optimize various functions to save space
- Clean up useless or duplicate code
