Haojian Zhuang 445b1e704e emmc: support CMD23 ...

Support CMD23. When CMD23 is used, CMD12 could be avoided.

Two scenarios:
1. CMD17 for single block, CMD18 + CMD12 for multiple blocks.
2. CMD23 + CMD18 for both single block and multiple blocks.

The emmc_init() should initialize whether CMD23 is supported
or not.
