Use ARRAY_SIZE macro instead of sizeof(x)/sizeof(x[0]). Some trailing
whitespaces are also removed.

Patch from Richard Purdie
This patch adds a check to see if the pxa i2c interface is enabled
before allowing it to be used and resets it if found to be disabled.
This automatically restores the interface if the device has been
suspended and resumed without causing any suspend/resume call ordering
issues.
The patch also fixes a build warning and adds an appropriate module
licence (the module is gpl according to the header).

This allows us to eliminate the casts in the drivers, and eventually
remove the use of the device_driver function pointer methods for
platform device drivers.
