pwm: Remove obsolete HAVE_PWM Kconfig symbol 

Before we had the PWM framework we used to have a barebone PWM api. The
HAVE_PWM Kconfig symbol used to be selected by the PWM drivers to specify
the PWM API is present in the kernel. Since the last legacy driver is gone
the HAVE_PWM symbol can go aswell.
