needed in later changes where we may not be able to lock the pic list lock
to perform a lookup, e.g. from within interrupt context.

TEGRA: Also attach gpioc to tegra_gpio driver. Forgotten in r299854.

TEGRA: Don't use common name 'gpio' for tegra specific GPIO driver.
Using commn name for different drivers breaks generic kernel creation.

INTRNG - redefine struct intr_map_data to avoid headers pollution. Each
struct associated with some type defined in enum intr_map_data_type
must have struct intr_map_data on the top of its own definition now.
When such structs are used, correct type and size must be filled in.

There are three such structs defined in sys/intr.h now. Their
definitions should be moved to corresponding headers by follow-up
commits.

While this change was propagated to all INTRNG like PICs,
pic_map_intr() method implementations were corrected on some places.
For this specific method, it's ensured by a caller that the 'data'
argument passed to this method is never NULL. Also, the return error
values were standardized there.

Import basic support for Nvidia Jetson TK1 board and tegra124 SoC.
The following pheripherals are supported: UART, MMC, AHCI, EHCI, PCIe, I2C,
PMIC, GPIO, CPU temperature and clock.

Note: The PCIe driver is pure mash at this moment. It will be reworked
immediately when both D5237 and D2579 enter the current tree.
