Add a new callback to handle softmmu paging. Return the page
details directly, instead of passing them indirectly to
tlb_set_page. Handle alignment simultaneously with paging so
that faults are handled with target-specific priority.
Route all calls of the two hooks through a tlb_fill_align
function local to cputlb.c.
As yet no targets implement the new hook.
As yet cputlb.c does not use the new alignment check.

Expose handle_bufioreq in xen_register_ioreq().
This is to allow machines to enable or disable buffered ioreqs.
No functional change since all callers still set it to
HVM_IOREQSRV_BUFIOREQ_ATOMIC.

hw/char/serial currently contains the implementation of both TYPE_SERIAL and
TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal
class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's
move the latter into its own module which makes the dependencies more obvious
and the code more tidy.
The includes and the dependencies have been converted mechanically except in the
hw/char directories which were updated manually. The result was compile-tested.
Now, only hw/char makes direct use of TYPE_SERIAL:
# grep -r -e "select SERIAL" | grep -v SERIAL_
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
hw/char/Kconfig: select SERIAL
# grep -r -e "/serial\\.h"
include/hw/char/serial-mm.h:#include "hw/char/serial.h"
hw/char/serial-pci-multi.c:#include "hw/char/serial.h"
hw/char/serial.c:#include "hw/char/serial.h"
hw/char/serial-isa.c:#include "hw/char/serial.h"

When riscv_load_firmware() loads an ELF, the ELF segment addresses are
used, not the passed-in firmware_load_addr. The machine models assume
the firmware entry point is what they provided for firmware_load_addr,
and use that address to generate the boot ROM, so if the ELF is linked
at any other address, the boot ROM will jump to empty memory.
Pass back the ELF entry point to use when generating the boot ROM, so
the boot ROM can jump to firmware loaded anywhere in RAM. For example,
on the virt machine, this allows using an OpenSBI fw_dynamic.elf built
with FW_TEXT_START values other than 0x80000000.

Remove the lm832x keyboard-and-pwm i2c device model. This
was only used by the n800 and n810 machines.
(Although this is an i2c device and so in theory available to create
on the command line, in practice it has an outbound IRQ line that the
machine model needs to wire up, and the only way to inject keys events
into it is to call the lm832x_key_event() function, so it isn't
in practice possible to use it separately from the n800/n810.)

Remove the tsc210x touchscreen controller device, which was
only used by the n800 and n810 and cheetah.
The uWireSlave struct is still used in omap1.c (at least for
compilation purposes -- nothing any longer calls omap_uwire_attach()
and so the struct's members will not be used at runtime), so
we move it into omap.h so we can delete tsc2xxx.h.

The Cadence GEM peripherals as configured for Zynq MPSoC and Versal
platforms have two priority queues with separate interrupt sources for
each. If the interrupt source for the second priority queue is not
connected, they work in polling mode only. This change connects the
second interrupt source for platforms where it is available. This patch
has been tested using the lwIP stack with a Xilinx-supplied driver from
their embeddedsw repository.
