[Patch] Shut up warnings from files under drivers/

[WANG Cong <xiyou.wangcong@gmail.com>]

Fix two kind of defined-but-not-used warnings.

One is due to defination of MODULE_DEVICE_TABLE, the
other is due to __devexit_p. The solution is just to
add proper directives to protect those usages.

Compile tests passed.
