Still there in v3.17-rc5 and next-20140918. So I submit yet another
trivial cleanup.

Done on top of next-20140918. Only tested by grepping the tree. Please
note that, obviously, nothing uses s5p_gpio_get_drvstr() or
s5p_gpio_set_drvstr().

Commit d78c16ccde96 ("ARM: SAMSUNG: Remove remaining legacy code")
removed the Kconfig symbol S5P_GPIO_DRVSTR. It didn't remove one check
for the related macro. Remove that check and the dead code it hides.
