[PATCH 4/9] hw/arm/tosa: Convert TYPE_TOSA_MISC_GPIO from SysBus to QDev

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

Drop the pointless TosaMiscGPIOState structure definition,
since it defaults to the size of the parent's type.

Nothing in TYPE_TOSA_MISC_GPIO access the SysBus API,
convert it to a plain QDev.
