Narrowly silence new (GCC 8.1+) warning (#290) 
Fixes #287

The warnings look like:
```
      Line 338 Char 37
      warning: 'void* memcpy(void*, const void*, size_t)' 
               writing to an object of type 'struct DmacDescriptor'
               with no trivial copy-assignment [-Wclass-memaccess]
```

c68c0b19ae Disable -Wimplicit-fallthrough in sections 
These two files contain code with switch statements,
where one case "fall through" to the next case.
As it's not currently clear if this is intentional or not,
rather than modifying the code in any way (regression risk),
use GCC diagnostic pragmas to disable this warning for
only these two files, with BUGBUG marking to encourage
review by someone more familiar with this code.

1a89b145ef Enhance warning output. 
Add comment to line GCC points finger at.
This is not intended to fix the warning.
Rather, it is intended to make it clearer
that this may need a deeper review before
determining what (if any) code change would
be appropriate.

e1e7b37ff3 Disable -Wimplicit-fallthrough for these two files. 
These two files contain code with multiple switch statements,
where one case "fall through" to the next case.
As it's not currently clear if this is intentional or not,
rather than modifying the code in any way (regression risk),
use GCC diagnostic pragmas to disable this warning for
only these two files, with BUGBUG marking to encourage
review by someone more familiar with this code.

4f80972c23 cast to uint32_t to avoid compiler warning 
that said, it's possible this api might return
a variety of non-zero codes.  code could benefit
from being updated (e.g., documenting return codes)

SAMD21: Fix freq clipping in SPI.h, allow 24 MHz SPI

a2c0a5b547 SAMD21: Fix freq clipping in SPI.h, allow 24 MHz SPI 
SPI clock freq previously clipped at MAX_SPI/2 (6 MHz) rather than MAX_SPI. Now works correctly.
Additionally, MAX_SPI set at 24 MHz on SAMD21. This is only slightly beyond spec and so far seems reliable with SD and SdFat tests on M0 Adalogger, eyes on HalloWing M0.
