[v3, 0/5] Add eSDHC UHS-I/HS200 mode support for ls1012a/ls1046a/ls208xa

[v3, 0/5] Add eSDHC UHS-I/HS200 mode support for ls1012a/ls1046a/ls208xa

[Yangbo Lu]

This patchset is to add eSDHC UHS-I/HS200 mode support for ls1012a/ls1046a/ls208xa.
Also add eSDHC node for ls1088a. Because eSDHC is not a standard SD controller,
the specific speed mode support depends on board's peripheral circuit for eSDHC.
So, we have to add these speed modes support on board dts file.

In additon, these dts patches depends on esdhc driver patches which just had been merged
on mmc.git. Otherwise, the UHS-I SD card and eMMC HS200 card would fail to be initialized,
but other cards still could work fine.

[Yangbo Lu]

This patch is to enable SD UHS-I mode and eMMC HS200 mode on
LS1046ARDB in dts. Also, the eSDHC peripheral clock must be used
instead of platform clock to support these modes.
