Don't set -pedantic-errors in CMAKE_C_FLAGS, it breaks check_symbol_exists()
Set -pedantic-errors in more specific variables like
CMAKE_C_FLAGS_DEBUG, CMAKE_C_FLAGS_RELEASE and
CMAKE_C_FLAGS_RELWITHDEBINFO.

picoproj: replace mmap() with more portable file stream operations
This makes picoproj compile for Windows, for instance.

picoproj: fix a typo
We have no am7xxx_get_info(), maybe this is a leftover of some older

am7xxx: fix setting the USB configuration
libusb_set_configuration() expects the bConfigurationValue of the
configuration we wish to activate as the second parameter.
The am7xxx devices we know have bConfigurationValue=2 for the first and
only configuration available in the descriptor, use this value.
While the libusb linux back-end looks forgiving on this one, without this
change the WinUSB back-end will fail with an error like:
