The HAVE_PWM symbol is only for legacy platforms that provide
the PWM API without using the generic framework. PXA platforms
use the generic PWM framework, after the commit "17b2b47 pwm:
Move PXA PWM driver to PWM framework".
In the case of "CONFIG_HAVE_PWM=y && CONFIG_PWM=n", PXA platforms
make the build errors as below. Thus, selecting HAVE_PWM should
be removed from PXA platforms.
