This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To match the SoC version and revision, 15 previous version
patchsets had tried many methods but all of them were rejected by reviewers.
Such as
- dts compatible method
- syscon method
- ifdef PPC method
- GUTS driver getting SVR method
Anrd suggested a soc_device_match method in v10, and this is the only available
method left now. This v11 patchset introduces the soc_device_match interface in
soc driver.

The first four patches of Yangbo are to add the GUTS driver. This is used to
register a soc device which contain soc version and revision information.
The other three patches introduce the soc_device_match method in soc driver
and apply it on esdhc driver to fix this bug.
