[PATCH] gpio: mvebu: fix sleeping-while-atomic in mvebu_gpio_level_irq_mask()

[Bartosz Golaszewski]

mvebu_gpio_write_level_mask() is called with a raw spinlock taken but
the underlying regmap uses a standard spinlock which can sleep on
RT_PREEMPT kernels. Add the .use_raw_spinlock attribute to the
appropriate regmap config.
