gpiolib: Fix crash on error in gpiochip_get_ngpios()
[ Upstream commit 7b4aebeecbbd5b5fe73e35fad3f62ed21aa7ef44 ]
The gpiochip_get_ngpios() uses chip_*() macros to print messages.
However these macros rely on gpiodev to be initialised and set,
which is not the case when called via bgpio_init(). In such a case
the printing messages will crash on NULL pointer dereference.
Replace chip_*() macros by the respective dev_*() ones to avoid
such crash.
Fixes: 55b2395e4e92 ("gpio: mmio: handle "ngpios" properly in bgpio_init()")
