Poking at the
MIPS jazz is the last user of the legacy esp_init() function so move creation
of the ESP device over to use qdev.
Note that the esp_reset and dma_enable qemu_irqs are currently unused and so
we do not wire these up and instead remove the variables to prevent the
compiler emitting unused variable w
