diskio: renamed print_device_info() to diskio_print_device_info()
platform/inga/dev: fixed busy wait timing in microSD read and write.
This should resolve almost all remaining sd card write errors.
platform/inga/dev: minor doc updates for microSD interface
platform/inga: Added makefile support for setting INGA revision with REV=<version>
diskio: replaced remaining microSD_* function calls with diskio-arch macros
platform/inga: moved micro sd power handling from sd driver to platform level

In current INGA revision the sd card blocks the spi when powered on,
thus power switching should be done on application level rather then in
the sd card driver.
Additionally, the driver might be used also in non-switchable setups later on.
