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.

Thierry as PWM maintainer has agreed to take this patch. Would be nice
to get some Acks from affected architectures. Russell, Ralf?
