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.

STMP378x and MX23 are the same and just relabeled. There is a
mach-stmp378x, however, it has a lot of reinvented interfaces, leaking
all sorts of mach-specific functions into the drivers. One example is
the dmaengine which does not use the linux dmaengine-API but some
privately exported symbols. This makes generic use of the drivers
impossible. mach-mxs does it better, so convert the board to mach-mxs.
After that, it is possible to delete all stmp-specific code which should
ease further ARM-consolidation.

Compile tested only due to no hardware (seems not available anymore).
