h1910 support in defconfiman

I would like to introduce the first step in adding h1910 support to
defconfigman.
There are some issues that I would like to get feedback from h1910
developers, before the file is added to the tree.
First, I could not classify following options:
SPI, SPI_DEBUG, SPI_MASTER and they were not added.
Second - defconfigman gives MTD support to every device - in this
case I am not sure if it is welcomed - I read about NAND support for
h1910 in wiki and there are/were some issues dangerous/untested (for
brave testers :) ).

The defconfig generated by defconfigman was tested - the kernel did
not build with it. It stopped on the same error as with the original
defconfig. Again - I am not able to test it - I don't own a h1910. So
please treat it as a template and not as complete solution.
