CLPS711X-target CPU can have a several FIQ interrupts. With this patch
we adds handling for a one which will be used for ALSA PCM later.
Since FIQ have a separate handler we only add "mask" and "unmask" calls
which will used for enable/disable_irq functions.

platform_device_unregister() only calls platform_device_del() and
platform_device_put(), thus use platform_device_unregister() to
simplify the code.

Also the documents in platform.c shows that platform_device_del
and platform_device_put must _only_ be externally called in error
cases.  All other usage is a bug.

The special checks for whether we have a base IRQ offset or not
is surplus if we use the simple IRQ domain. The IRQ offset
zero will be interpreted as a linear domain case.

Plus this makes sure we allocate descriptors where need be, or
warn if they are preallocated with SPARSE_IRQ.

The code in the em driver seems to want to try to do the job of
the linear IRQ domain (allocate descriptors and grab a virtual
range). So why not just use the linear IRQ domain? The code is
now cut down so we don't need isolated functions for this.

Also note that we use irq_create_mapping() to make sure
descriptors are allocated for these IRQs.

Also fixed the FIXME to remove the domain after use.

The MVEBU driver probably just wants a few IRQs. Using the simple
domain has the upside of allocating IRQ descriptors if need be,
especially in a SPARSE_IRQ environment.

The Tegra driver tries to do the work of irq_domain_add_linear()
by reserving a bunch of descriptors somewhere and keeping track
of the base offset, then calling irq_domain_add_legacy(). Let's
stop doing that and simply use the linear IRQ domain.

For this to work: use irq_create_mapping() in the IRQ iterator
so that the descriptors get allocated here.

Add .get_direction callback to gpio_chip. This allows gpiolib
to check the current direction of a gpio.
Used to show the correct gpio direction in sysfs and debug entries.

If callback is not set then gpiolib will work as previously;

The gpio_export function uses nested if statements and the status
variable to handle the failure cases. This makes the function logic
difficult to follow. Refactor the code to abort immediately on failure
using goto. This makes the code slightly longer, but significantly
reduces the nesting and number of split lines and makes the code easier
to read.
