DSI one shot support requires register access in the tegra framebuffer to
poke the frame trigger bit (with both the trigger bit and the tearing effect
signal are high, a frame of pixels will be sent to the panel). The boot args
must also be expanded to have a "use tearing effect" flag.
tegra RM: Expanded Display clock configuration options.
Added an option for restricted Display clock synchronization with MIPI
PLL - select MIPI PLL as a pixel clock source, but preserve PLL settings.
To specify this option flag NvRmClockConfig_InternalClockForPads should
be set by RM client along with NvRmClockConfig_MipiSync flag (in the
absence of the former flag, MIPI PLL can be re-configured at RM discretion
- current behavior).

Convert /dev/nvos to a general purpose node, /dev/nvos and a super
user node, /dev/knvos. /dev/nvos exposes semaphore related
functionality whereas /dev/knvos will be used for interrupt
and memory management. Track the semaphores in a rbtree
so that we do not stomp on anybody else's space and corrupt
the memory.

integrate files from android-tegra-2.6.29 branch to build NvOs
changes from previous branch:
* nvos_ioctl.h moved to top-level include/ directory
* tegra ATAG value and structure declaration moved to nvos.c
* cache and memory fence calls updated to match new kernel APIs
* PhysicalMemMap and PhysicalMemUnmap just call ioremap, which handles
static vs dynamic remapping internally.
