This could be generally useful and more specifically is a
prerequisite for issue #178.

The declaration seems to be misplaced compared to all other similar structs.
It's also a prerequisite for introducing the _replace hook for spi_lsbmode(),
per issue #178.

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.

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

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.

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.
