HID: Kconfig: Fix build error from CONFIG_HID_HAPTIC

Temporarily change CONFIG_HID_HAPTIC to be bool instead of tristate, until
we implement a permanent solution.

Recently the CONFIG_HID_HAPTIC Kconfig option was reported as causing
the following build errors:

  MODPOST Module.symvers
ERROR: modpost: "hid_haptic_init" [drivers/hid/hid-multitouch.ko] undefined!
ERROR: modpost: "hid_haptic_pressure_increase" [drivers/hid/hid-multitouch.ko] undefined!
ERROR: modpost: "hid_haptic_check_pressure_unit" [drivers/hid/hid-multitouch.ko] undefined!

make[3]: *** [/home/thl/var/linux.dev/scripts/Makefile.modpost:147: Module.symvers] Error 1

when the kernel is compiled with the following configuration:

CONFIG_HID=y
CONFIG_HID_MULTITOUCH=m
CONFIG_HID_HAPTIC=m

To resolve this, temporarily change the CONFIG_HID_HAPTIC option to be
bool, until we arrive at a permanent solution to enable CONFIG_HID_HAPTIC
to be tristate.
