DSET/DCLR registers only works on output pins. Add corresponding
BGPIOF_NO_SET_ON_INPUT flag to bgpio_init call to fix direction_out
behavior.

gpiochip_set_chained_irqchip() would assign a chained handler
to a GPIO chip. We now populate struct gpio_irq_chip for all
chained GPIO irqchips so drop this function.

We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.
For chained irqchips this is a pretty straight-forward
conversion.
This driver requests the IRQ directly in the driver so it
differs a bit from the others.

Use the new helper that wraps the calls to platform_get_resource()
and devm_ioremap_resource() together.

This fixes the kernel complains:
gpio gpiochip1: (1e000600.gpio-bank1): detected irqchip that is shared
with multiple gpiochips: please fix the driver.
gpio gpiochip2: (1e000600.gpio-bank2): detected irqchip that is shared
with multiple gpiochips: please fix the driver.

The error cases of mediatek_gpio_bank_probe() would go unnoticed (except
for the dev_err() messages). The probe function should return an error
if one of the banks failed to initialize properly indicated by
not returning non-0.

kasprintf() may return NULL on failure of internal allocation thus the
assigned label is not safe if not explicitly checked. On error
mediatek_gpio_bank_probe() returns negative values so -ENOMEM in the
(unlikely) failure case should be fine here.

This fixes some syntactic nits that makes the GPIO maintainer
happier. It is way easier to show by example and do it myself
than to try to explain it with comments. It's just my personal
taste of minimalism.
