tegra2 hangs if fuse registers are accessed during an apb dma
operation. war is to use apb dma to read/write fuse registers
instead.

are restored.

Tegra host controller will time the resume operation to clear the bit
when the port control state switches to HS or FS Idle. This behavior
is different from EHCI where the host controller driver is required
to set this bit to a zero after the resume duration is timed in the
driver.
Poll PORT_SUSPEND bit till the suspend is completed. Write PORT_RESUME to 0
to clear PORT_SUSPEND bit.
Disable disconnect detection during resume.

This fixes incorrect colors drawn by clients such as fbconsole. As
described by skeletonfb's fb_setcolreg: "The values supplied have a 16
bit magnitude which needs to be scaled in this function for the
hardware."
Tested with both r8g8b8 and r5g6b5 pixel depths and fbconsole.

- Added "single buffer continuous DMA" mode in addition to the
"double buffer continuous DMA" mode that is already implemented
- Changed the queuing of next buffer to be more flexible for
continuous DMA. It can now get in-flight right after a transfer
starts, or whenever the client enqueues a buffer.

If the console_sem was held while the system was rebooted, the messages
in the temporary logbuffer would not have propogated to all the console
drivers.
This force releases the console sem if it failed to be acquired.
