With the removal of the PMU reservation code and the introduction of devicetree bindings for the CPU PMU, the enumeration is no longer required. This patch removes the enumeration and updates the various CPU PMU platform devices so that they no longer pass an .id field referring to identify the PMU type.

Also, there is no actual code dependency between the platform and the gpio leds driver. Without this patch, building without LEDS_CLASS esults in: drivers/built-in.o: In function `create_gpio_led.part.2': governor_userspace.c:(.devinit.text+0x5a58): undefined reference to `led_classdev_register' drivers/built-in.o: In function `gpio_led_remove': governor_userspace.c:(.devexit.text+0x6b8): undefined reference to `led_classdev_unregister' This reverts 8733f53c6 "ARM: ux500: Kconfig: Compile in leds-gpio support for Snowball" that introduced the regression and did not provide a helpful explanation. In order to leave the GPIO LED code still present in normal builds, this also enables the symbol in u8500_defconfig, in addition to the other LED drivers that are already selected there.

Add CONFIG_NEED_MACH_GPIO_H and make platforns select it if they need gpio.h. This is platforms that define __GPIOLIB_COMPLEX or have lots of implicit includes pulled in by mach/gpio.h. at91 and omap have gpio clean-up pending and can drop CONFIG_NEED_MACH_GPIO_H once that is in.
