drm/nouveau/gpio: reimplement as nouveau_gpio.c, fixing a number of issues
- moves out of nouveau_bios.c and demagics the logical state definitions
- simplifies chipset-specific driver interface
- makes most of gpio irq handling common, will use for nv4x hpd later
- api extended to allow both direct gpio access, and access using the
logical function states
- api extended to allow for future use of gpio extender chips
- pre-nv50 was handled very badly, the main issue being that all GPIOs
were being treated as output-only.
- fixes nvd0 so gpio changes actually stick, magic reg needs bashing

drm/nouveau: use system_wq instead of dev_priv->wq
With cmwq, there's no reason for nouveau to use a dedicated workqueue.
Drop dev_priv->wq and use system_wq instead. Each work item is sync
flushed when the containing structure is unregistered/destroyed.
Note that this change also makes sure that nv50_gpio_handler is not
freed while the contained work item is still running.

drm/nv50: rework PGPIO IRQ handling and hotplug detection
Allows callers to install their own handlers for when a GPIO line
changes state (such as for hotplug detect).
This also fixes a bug where we weren't acknowledging the GPIO IRQ
until after the bottom half had run, causing a severe IRQ storm
in some cases.
