ide: add ->tf_load and ->tf_read methods
* Add ->tf_load and ->tf_read methods to ide_hwif_t and set the default
methods in default_hwif_transport().
* Use ->tf_{load,read} instead o calling ide_tf_{load,read}() directly.
* Make ide_tf_{load,read}() static.
There should be no functional changes caused by this patch.
