1. No .c file should include a "Public Types" section. Only a header file can define a public type. A .c file can only define a private type. Several files contained private type definitions. The section that they were defined in, however, was incorrectly named "Public Types." Those were easilty changed to "Private Types" which is what they are.
2. No .c file should include a "Public Function Prototypes" section. All global function prototypes should be provided via a header file and never declared with a .c file.
For No. 2, I corrected as many cases as was reasonable for the time that I had available. But there are still a dozen or so .c files that declare "Public Function Prototypes" within a .c file. This is bad programming style. These declarations should all be moved to the proper header files.

Add Imxrt usdhc insert or remove detection (#43)
* Add usdhc card insertion and removal detection using interrupt for imxrt.
* Add interrupt handle when usdhc insert or remove.
* Simplify EINTR/ECANCEL error handling
1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx
* Unify the void cast usage
1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro
(1) unifies the iomux definitions - previously some pins had them, and some didn't. This effectively made it impossible to use the pinmuxes without editing the header file in the standard distribution tree.
(2) unifies the pin definitions so that every pin now has a suffix. This makes it *much* easier to see when a pin is in use in your code, because it will always have a definition in your board.h file.
For anyone who is already using this CPU, a couple of small changes are needed to existing code;
In respect of (1) add IOMUX decorators to your pin definitions. You will find defaults in haardware/imxrt_iomux.h. Every pin should have a IOMUX decorator and in general the defaults should be OK. So while previously in your board.h file you might have had;
You will now have;
In respect of (2) you will need to add selectors for any function that previously only had one pinning option. There aren't many of those but LPUART1 is a good example. That just means adding into your board.h something like;
Remove hardcoded -DCLOCK_MONOTONIC from CFLAGS in Make.defs of several configurations. That defintiion is now automatically adding this define when CONFIG_LIBCXX=y.
