Michael Buesch cef678b2db extmod/machine_i2c: Fix buffer overrun if 'addrsize' is bigger than 32. 
The memory operation functions read_mem() and write_mem() create a
temporary buffer on the local C stack for the address bytes with the size
of 4 bytes.  This buffer is filled in a loop from the user supplied address
and address length.  If the user supplied 'addrsize' is bigger than 32, the
local buffer is overrun.

Fix this by raising an exception for invalid 'addrsize' values.
