Looking at all structs as to where we can pack them a little better, and
calling out the padding/stride at the end for future expansion.

Benjamin Walsh d340d4cb3f device: use DEVICE_INIT everwhere
This is the last step before obsoleting DEVICE_DEFINE() and
DEVICE_INIT_CONFIG_DEFINE().

Benjamin Walsh 0303d8cab9 device: rename SYS_DEFINE_DEVICE()
Rename it to DEVICE_DEFINE() so that it fits in the 'device' namespace.

Benjamin Walsh bfc27206b2 device: rename DECLARE_DEVICE_INIT_CONFIG()
Rename it to DEVICE_INIT_CONFIG_DEFINE(), because (a) it was not fitting
in any namespace and (b) it is not used to declare, but rather define a
object.

Anas Nashif 6bca3724c1 drivers: set default priority for drivers
Use a default priority to avoid Kconfig blocking when priority
is not set in SoC or Board.

Dmitriy Korovkin dcda679c72 gpio, pwm, rgb lcd: Replace polling i2c requests
Now that i2c_transfer/i2c_read/i2c_write are fully synchronous, no need
to use the polling based function.

Dmitriy Korovkin 57f2741e4f init: Implement fine-grained initialization policy
Put initialization priorities as device driver Kconfig
parameter.

Initialization priority value for each platform is defined
in the platform Kconfig file.

Drivers and platform code use SYS_DEFINE_DEVICE to add
and initialization function.

Johan Kruger 7a9fa51b61 pwm: Changes to PWM driver for the PCA9685.
- Changed behavior of duty cycle to have the signal ON time as the
  duty percentage instead off the off time. Note however, this requires
  that the off time is controlled. The behavior seems to be inverse of
  what the user will expect on the header IO.

The polling I2C write function guarantees the write operation
is completed. It is to make sure each write has been commited.

Daniel Leung 8c27aedb79 pwm: pca9685: remove call to i2c_configure for every write
The I2C controller should have been already setup before this driver.

Since the only use right now is on Gelileo and I2C_DW driver. it is
safe to remove the i2c_configure() call now as the driver has default
configuration at boot.
