Compile with GNU ARM Embedded 6

[janjongboom]

These were the changes that I required to make cryptoauthlib compile on Mbed OS 5 with GNU ARM Embedded 6. I assume the struct names in atca_iface.h are not required. The change in atca_command.h was required because size_t was not defined.

Out of curiosity what was your include order? We build on Linux platforms with gcc quite regularly (raspberry pi), yocto, etc.

I encountered a similar problem, in my case I use a yocto project that uses the "arm-poky-linux-gnueabi-g++ (GCC) 7.3.0" compiler and this returns the next error:
...../usr/include/cryptoauthlib/atca_iface.h:74:16: error: ‘struct::::ATCAI2C’ invalid; an anonymous union can only have non-static data members [-fpermissive]
struct ATCAI2C
Removing all the struct names in atca_iface.h solved the issue too.
