[PATCH 2/9] fix: suspended wrong USB port on Acer n35

[Pinkava J.]

There is bug in USB setup code for Acer n35 (it is related directly to s3c2410,
see doc). We want suspend host port (is not connected) but device port should be
active.

2.6.34-rc6 should still have working gpio_set_value/gpio_direction_output
calls in it, please update patch 8 to at-least use these.

Acer n35 patches

[Pinkava J.]

I might update patches to use new GPIO infrastructure for S3C already in
samsung-next (genecit s3c calls instead of s3c2410 GPIO calls)

I'm going to hold this one pending the merge of the gpio updates, since
these calls are going away.
