ARM: mxs: don't select HAVE_PWM

The HAVE_PWM symbol is only for legacy platforms that provide the PWM API without using the generic framework. MXS actually uses that framework, and selecting the symbol anyway might cause build errors like

drivers/built-in.o: In function `pwm_beeper_resume':
:(.text+0x1f4fc0): undefined reference to pwm_config' :(.text+0x1f4fc8): undefined reference to pwm_enable' drivers/built-in.o: In function `pwm_beeper_suspend':
:(.text+0x1f4ffc): undefined reference to `pwm_disable'

when CONFIG_PWM is disabled.
