[PULL 08/24] esp: use correct type for esp_dma_enable() in sysbus_esp_gpio_demux()

[Paolo Bonzini]

From: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

The call to esp_dma_enable() was being made with the SYSBUS_ESP type instead of
the ESP type. This meant that when GPIO 1 was being used to trigger a DMA
request from an external DMA controller, the setting of ESPState's dma_enabled
field would clobber unknown memory whilst the dma_cb callback pointer would
typically return NULL so the DMA request would never start.
