Subject: [v16, 0/7] Fix eSDHC host version register bug

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.

---
Changes for v15:
	- Dropped patch 'dt: bindings: update Freescale DCFG compatible'
	  since the work had been done by below patch on ShawnGuo's linux tree.
	  'dt-bindings: fsl: add LS1043A/LS1046A/LS2080A compatible for SCFG
	   and DCFG'
	- Fixed error code issue in guts driver
Changes for v16:
	- Dropped patch 'powerpc/fsl: move mpc85xx.h to include/linux/fsl'
	- Added a bug-fix patch from Geert
