[PATCH] leds: make LEDS_GPIO_REGISTER depend on NEW_LEDS

[Axel Lin <axel.lin@gmail.com>]

Commit 4440673a "leds: provide helper to register "leds-gpio" devices"
adds "config LEDS_GPIO_REGISTER" in drivers/leds/Kconfig.
However, config LEDS_GPIO_REGISTER does not depend on NEW_LEDS, while executing
make menuconfig a side-effect is observed that the "LED drivers" and
"LED Triggers" are now displayed at the same level of "LED Support".
( They was in sub-menu of "LED Support" before the commit. )

This patch makes LEDS_GPIO_REGISTER depend on NEW_LEDS to correctly show
"LED drivers" and "LED Triggers" in sub-menu of "LED Support".

Besides, LEDS_GPIO_REGISTER is set to be bool but no description.  Thus I
cannot find LEDS_GPIO_REGISTER config option while executing make menuconfig.

This patch also adds the description for LEDS_GPIO_REGISTER so the option can
be correctly displayed.
