3665ff03c1 mmc: sdhci: Change O2 Host HS200 mode clock frequency to 200MHz
O2 SD Host HS200 mode clock frequency current is 208MHz, should be changed
to 200MHz to meet specification.

57322d542f mmc: sdhci: Add support for O2 eMMC HS200 mode
When use eMMC as boot device, the eMMC signaling voltage is tied to 1.8v
fixed output voltage, bios can set o2 sd host controller PCI configuration
register 0x308 bit4 to 1 to let driver skip 3.3v signaling voltage and
direct use 1.8v singling voltage in eMMC initialize process.

361eeda0ca mmc: sdhci-pci: Tidy o2micro definitions
We keep PCI Ids in sdhci-pci.h and the O2-specific definitions belong in
sdhci-pci-o2micro.c. Move those definitions accordingly. Remove unused O2
definitions in sdhci-pci-core.c. The 3 o2micro external function
declarations might as well be in sdhci-pci.h as well, so move them there
and get rid of sdhci-pci-o2micro.h entirely.

30cf2803b2 mmc: sdhci-pci: Let suspend/resume callbacks replace default callbacks
The suspend / resume callbacks lack the flexibility to allow a device to
specify a different function entirely. Change them around so that device
functions are called directly and they in turn can call the default
implementations if needed.

b7813f0fe9 mmc: sdhci-pci: Conditionally compile pm sleep functions
It is confusing to have some parts of suspend / resume under conditional
compilation and some parts not. Use conditional compilation everywhere.

659c9bc114 mmc: sdhci-pci: Build o2micro support in the same module
sdhci-pci-o2micro.c contains no initialisation and its functions are only
called from shdci-pci.c, so there is no reason for it to be a separate
module, let alone or for it to always be built-in.

- Rename sdhci-pci.c to sdhci-pci-core.c so that the sdhci-pci module
  can be built from multiple source files
- Add sdhci-pci-o2micro.c to it
- Remove redundant exports
