video: tegra: host: make nvhost_get_host inline

- nvhost_get_host returns host1x's master driver's
private data
- this host1x master is parent for all its modules.
however, it does not have a parent of its own
- so the debug_not_idle causes crash when there is an
outstanding reference count on host1x by some module
during suspend sequence
- with this change, debug_not_idle returns error to
pm core if host1x has an outstanding ref count. pm core
then safely aborts the suspend and does resume

gpio: gpiolib: Support for open drain/collector gpios

Adding support for the open drain gpio on which client
can specify the open drain property through GPIO flag
GPIOF_OPEN_DRAIN at the time of gpio request.
The open drain pins are normally pulled high and it
cannot be driven to output with value of 1 and so
when client request for setting the pin to HIGH, the
gpio will be set to input direction to make pin in tristate
and hence PULL-UP on pins will make the state to HIGH.
The open drain pin can be driven to LOW by setting output
with value of 0.

smp_twd: make sure timer is stopped before registering it

On secondary CPUs, the Timer Control Register is not reset
to a sane value before the timer is registered, and the TRM
doesn't seem to indicate any reset value either. In some cases,
the kernel will take an interrupt too early, depending on what
junk was present in the registers at reset time.

The fix is to set the Timer Control Register to 0 before
registering the clock_event_device and enabling the interrupt.

Problem seen on VE (Cortex A5) and Tegra.
