We must unlock the mutex *after* the `out` label or we'd trigger a
deadlock in error path.

When using bgpio_init with a gpiochip acting as a GPO (output only), the
gpiochip ops `direction_input` was set to `bgpio_simple_dir_in` by
default but we have no input ability.
Adding this flag allows to set a valid ops for the `direction_output`
ops without setting a valid ops for `direction_input` by default.

In some Amlogic SoCs, to save register space or due to some
abnormal arrangements, two sets of pins share one mux register.
A group starting from pin0 is the main pin group, which acquires
the register address through DTS and has management permissions,
but the register bit offset is undetermined.
Another GPIO group as a subordinate group. Some pins mux use share
register and bit offset from bit0 . But this group do not have
register management permissions.
This submission implements this situation.
