serial: atmel_serial: remove atmel open/close hooks

After serial_at91.h was removed the atmel_open/close_hook code is now useless.

Hi,

This patch depends on [RFC 3/3] ARM/AVR32: get rid of serial_at91.h patch from Russell King.

Patch based on current linux-next with "[RFC 3/3] ARM/AVR32: get rid of serial_at91.h" patch on top. There is a small conflict with Russell's patch
in next now due to another header change.

If there is another tree this patch should be based on please let me know.

regards
Joachim Eastwood
