pwm: add HAS_IOMEM dependency to PWM_FSL_FTM
Ran into this on UML:
drivers/built-in.o: In function `fsl_pwm_probe':
linux/drivers/pwm/pwm-fsl-ftm.c:436: undefined reference to `devm_ioremap_resource'
collect2: error: ld returned 1 exit status
devm_ioremap_resource() is defined only when HAS_IOMEM is selected.
