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.

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.

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.

It is confusing to have some parts of suspend / resume under conditional
compilation and some parts not. Use conditional compilation everywhere.

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
