SH4: Switch serial emulation to qemu_irq
This patches makes SH serial emulation use qemu_irq in its interface.
* hw/sh.h (sh_serial_init): Take qemu_irq, not intc_source.
* hw/sh7750.c (sh7750_init): Adjust.
* hw/sh_intc.c (sh_intc_set_irq): Don't assert or deassert
irq more than once.
* hw/sh_serial.c (sh_serial_state): Use qemu_irq, not intc_source.
(sh_serial_clear_fifo, sh_serial_ioport_write)
(sh_serial_receive_byte): Adjust.
(sh_serial_init): Take qemu_irq, not intc_source.
