The USB host drivers need platform data to be defined on pxa168 and pxa910, but the conditionals used in the devices.c file only work if the drivers are built-in. This patch fixes the definition by changing the #ifdef to #if IS_ENABLED(), which works both for built-in and modular Kconfig symbols. I found one specific problem using 'randconfig' builds, but for consistency, this patch uses IS_ENABLED() for all Kconfig symbols in these three files.
