On 07 OCT 2010 you advised to integrate GPIO handling (reset and
SPI-enable) into CODEC code flow.

Now Hartley suggested to move GPIO handling to platform code. This makes
sense, as SPI-enable will be managed automatically, and reset is also
more related to platform (depending on schematics, inversion and so on).

As for me, I think handle it in platform code is better. So we can now
remove all the GPIO code and cs4271_platform_data structure from CS4271
