The 608 MHz table entry would incorrectly produce a 760 MHz
clock for input clocks of 12 MHz, 13 MHz, or 26 MHz.

Fuses must be initialized before clocks, so clocks can
determine the maximum cpu frequency. Clocks must be
initialized before DMA, so DMA can enable the clock.
Once DMA is initialized, all fuses accesses must go
through DMA to avoid a hardware bug.

There is a dependency loop between fuses, clocks, and APBDMA.
If dma is enabled, fuse reads must go through APBDMA to avoid
corruption due to a hw bug. APBDMA requires a clock to be
enabled. Clocks must read a fuse to determine allowable cpu
frequencies.
Separate out the fuse DMA initialization, and allow the fuse
read and write functions to be called without using DMA before
the DMA initialization has been completed. Access to the fuses
before APBDMA is initialized won't hit the hardware bug because
nothing else can be using DMA.

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

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.
