When operating on the SCIF, process all the received characters, as long
as the FIFO can handle them.

As stated before, devices can be little, big or native endian. The
target endianness is not of their concern, so we need to push things
down a level.
This patch adds a parameter to cpu_register_io_memory that allows a
device to choose its endianness. For now, all devices simply choose
native endian, because that's the same behavior as before.

When building with -DNDEBUG, assert(0) will not stop execution
so it must not be used for abnormal termination.
Use cpu_abort() when in CPU context, abort() otherwise.

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

Some not so obvious bits, slirp and Xen were left alone for the time
being.

The parameter is always zero except when registering the three internal
io regions (ROM, unassigned, notdirty). Remove the parameter to reduce
the API's power, thus facilitating future change.

Include assert.h from qemu-common.h and remove other direct uses.
cpu-all.h still need to include it because of the dyngen-exec.h hacks

This patch simply implement one register of SH4's SCI := Serial Communication Interface.
R2D evaluation board uses SCI for SPI connection. So, Linux kernel for R2D with
default configuration causes a QEMU assertion failure when it initializes SPI driver.
This patch avoids it and reduces the kernel config modification work for QEMU.
Completing SCI implementation task is left. Other board support is desirable to confirm
this task, which uses SCI for a serial terminal.

Main purpose of this is to delete
*physical = address & 0x1fffffff;
at target-sh4/helper.c:449, using new mmio rule introduced by #5849
This masking is a nice trick to realize P4/A7 duality of SH registers.
But, IMHO, it is logically wrong.
Most of SH4 cpu control registers in P4 area(0xfc000000...0xffffffff) have
one more address called A7 which is usually P4 address with upper 3bits masked.
This is an address only appears in TLB's physical address part.
Current code use trick writing drivers as if they are really in A7
(that's why you see many *_A7 in hw/sh*.c), and using translation P4 to A7.

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.

Add receive character feature to SH4 SCIF.
SH4-SCI feature implementation work is left.
