Subject: [PATCH] Do not cast pointers to different size integers

It will work only on little endian machines.

Fix clang warning
pn53x-tamashell.c:163:40: warning: cast from 'uint8_t *' (aka 'unsigned char *')
      to 'unsigned int *' increases required alignment from 1 to 4
      [-Wcast-align]
      size = sscanf(cmd+offset, "%2x", (unsigned int*)&byte);
                                       ^~~~~~~~~~~~~~~~~~~~
