MLK-10795-5 camera: use gpio_set_value_cansleep instead of gpio_set_value
The reason is in spi gpio driver (drivers/gpio/gpio-74x164.c) the 'can_sleep'
property is set true as follows.
chip->gpio_chip.can_sleep = true;
Then gpio_set_value() calls gpiod_set_raw_value(), in which it checkes
'can_sleep' property.
WARN_ON(desc->chip->can_sleep);
Use gpio_set_value_cansleep instead to avoid the kernel warning message.
