[PATCH] Input: psmouse - Fix build error of multiple definition

[YueHaibing]

trackpoint_detect() should be static inline while
CONFIG_MOUSE_PS2_TRACKPOINT is not set. otherwire,we
got building fails:

drivers/input/mouse/alps.o: In function `trackpoint_detect':
alps.c:(.text+0x8e00): multiple definition of `trackpoint_detect'
drivers/input/mouse/psmouse-base.o:psmouse-base.c:(.text+0x1b50): first defined here
