Hi everyone,
The Allwinner A31 SoC has a quite different clock tree and structure that the
other Allwinner SoCs that we already merged, so it requires more work than what
we had for the other SoCs until now.
It's also an opportunity to do some minor cleanup/refactoring to land the new
code
The A31 has a mostly different clock set compared to the other older
SoCs currently supported in the Allwinner clock driver.
Add support for the basic useful clocks. The other ones will come in
eventually.

Now that the clock driver has support for the A31 clocks, we can add
them to the DTSI and start using them in the relevant hardware blocks.

We can take advantage of the fact that bit 29 is hard-wired
to zero in register TRIO_TILE_PIO_REGION_SETUP_CFG_ADDR.
This is handy since at the moment we only allocate one 4GB
region for vmalloc, and with this change we can allocate
four or more TRIO MACs without using up all the vmalloc space.
To enable this functionality, configure CONFIG_TILE_PCI_IO. Without
this flag, the kernel still assigns I/O address ranges to the
devices, but no TRIO resource and mapping support is provided.
We assign disjoint I/O address ranges to separate PCIe domains.
