RST line is not used even when configured

[iohugo]

If you specify the RST line, it is configured in init, but the reset() function is never called from _init() or indeed anywhere else, leaving the RST line driven low - ie, display is in reset.

You can't neatly work around this by calling reset() from your code, because it will happen after the SPI setup commands have been sent.

The fix would be to call reset() at the top of _init() in the driver.
