[PATCH] ARM: pxa: include linux/leds.h

Arnd Bergmann [off-list ref] writes:

When the header is not included implicitly, we get a build failure:

arch/arm/mach-pxa/idp.c:205:22: error: field 'cdev' has incomplete type
  struct led_classdev     cdev;

This adds an explicit #include.

Sure, pushed into pxa/for-next, I hope it's not troublesome enough to include it
in the 4.10 cycle pxa fixes which is ... empty so far.

Cheers.
