41956b07d6 pwm.c: cache period 
There is an issue that  mraa_pwm_write would fail, because mraa_pwm_read
would fail and return 0.  When the read fails, journalctl shows an
error:
Dec 28 18:01:38 Edison libmraa[365]: pwm: Error in reading period

So now trying version, where the pwm object caches the period, that is
updated whenever you do a read or write of the period.  Side benefit is
that the write should be sped up.

19d7dad364 i2c: remove smbus helper library & clean up command use in API 
This commit changes the mraa_i2c_read() API call behaviour, a register should
now always be set when using this call. The smbus helper library is no longer
required since the code is now all contained from i2c.c which avoids multiple
function calls

3865bebe8d mmap: remove implementation of mmap gpio 
Instead of trying to have an implementation that covers most platforms
Leave all mmap up to platform definition. Through function pointers.

gpio_mmap_setup sets up the mmap

Within the internal gpio context struct two more function pointers now
exist mmap_read & mmap_write. They exist there so each context can its
own function for handling a write and read.

32d8a6f0ca syslog: remove all fprintf calls and use syslog instead 
Syslog is now used for all error messages, return values in the code should be
used by programmers to see the status of the library/board and syslog can be
used to see quickly from a debugging perspective what has gone wrong. A few
cosmetics where improved as well as a mraa_set_log_level() call where the
syslog log mask can be set directly from libmraa.
