In previous commit, mstatus.mie was set when creating a new task
but this change was incorrect and had a side effect such that
a machine interrupt would be enabled just before returning from
interrupt handling routine to switch context.
Also, mstatus.mpp is set to machine mode in up_get_newintctx()
instead of fe310_dispatch_irq().
