This patchset includes a __weak attributed pwm apis in pwm.h and
a ff-memless based isa1200 driver.

ISA1200 chip can operate in two modes and if the chip has been
configured for pwm-generation mode, which doesn't use pwm standard
apis then it'd encounter compilation errors if the host doesn't
support PWM. This driver is based on Park's isa1200 driver that uses
haptic class.
