gpiolib: output basic details and consolidate gpio device drivers
This patch adds a kernel message, containing GPIO range and device name on successful device registration, and removes duplicate messages from the following drivers: * gpio-adp5588 * gpio-bt8xx * gpio-cs5535 * gpio-janz-ttl * gpio-nomadik * gpio-pcf857x * gpio-xilinx * drivers/of/gpio.c Signed-off-by: Hartmut Knaack <knaack.h@gmx.de> [grant.likely@secretlab.ca: squashed 2 patches together] Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
