d258c82d52 bdk: sdmmc: add UHS DDR200 support 
The bdk flag BDK_SDMMC_UHS_DDR200_SUPPORT can be used to enable it.

SD Card DDR200 (DDR208) support

Proper procedure:
1. Check that Vendor Specific Command System is supported.
   Used as Enable DDR200 Bus.
2. Enable DDR200 bus mode via setting 14 to Group 2 via CMD6.
   Access Mode group is left to default 0 (SDR12).
3. Setup clock to 200 or 208 MHz.
4. Set host to DDR bus mode that supports such high clocks.
   Some hosts have special mode, others use DDR50 and others HS400.
5. Execute Tuning.

The true validation that this value in Group 2 activates it, is that DDR50 bus
and clocks/timings work fully after that point.

On Tegra X1, that can be done with DDR50 host mode.
Tuning though can't be done automatically on any DDR mode.
So it needs to be done manually and selected tap will be applied from the
biggest sampling window.

Finally, all that simply works, because the marketing materials for DDR200 are
basically overstatements to sell the feature. DDR200 is simply SDR104 in DDR mode,
so sampling on rising and falling edge and with variable output data window.
It can be supported by any host that is fast enough to support DDR at 200/208MHz
and can do hw/sw tuning for finding the proper sampling window in that mode.

Using a SDMMC controller on DDR200 mode at 400MHz, has latency allowance implications. The MC/EMC must be clocked enough to be able to serve the requests in time (512B in 1.28 ns).

55e01ca735 bdk: sd: improve init error handling 
- Management of sd init done is now on sd init retry function
 Also manages inserted, since it can set the sd init done to false if failed
- Init will now always check if SD is also initialized, since it doesn't manage it anymore. Because of that, mounting is no longer forced, but checked first.
- Unmount/End will now always set the sd as unmounted, since no data residue is expected after the fact

The above will improve handling of faulty SD cards or faulty SD readers.

605f270f98 bdk: usb: fix a race condition in USB2 stack 
When RAM is slow (no training), it's possible to have the stack failing to negotiate configuration successfully.

The race condition is caused by not flushing cache before sending a configuration packet reply.
Although, cache is write-through, this needs to happen.

e09710e3eb bdk: fatfs: mkfs alignment changes 
- Default data alignment is now 1MB **when it's not set**
- Default volume alignment is now based on data alignment and not hardcoded to 16MB.
- Change max allowed alignment to 64MB.

The above changes allow selecting alignments for volume and data between 1MB and 64MB.
(From the previous 1 to 16MB for data and 16MB for volume).
