leds: expresswire: Don't depend on NEW_LEDS
The ExpressWire library does not depend on NEW_LEDS and selecting it
from a subsystem other than LEDs may cause Kconfig warnings:
WARNING: unmet direct dependencies detected for LEDS_EXPRESSWIRE
Depends on [n]: NEW_LEDS [=n] && GPIOLIB [=y]
Selected by [y]:
- BACKLIGHT_KTD2801 [=y] && HAS_IOMEM [=y] && BACKLIGHT_CLASS_DEVICE [=y]
Move it out of the "if NEW_LEDS" block to allow selection from other
subsystems (in particular backlight) without raising this warning.
