VIA needs to be able to poll the ADB interface and to read/write data
from/to the bus.
This patch adds functions allowing that.

Inside the 680x0 Macintosh, VIA (Versatile Interface Adapter) is used
to interface the keyboard, Mouse, and real-time clock. It also provides
control line for the floppy disk driver, video interface, sound circuitry
and serial interface.
This implementation is based on the MOS6522 object.

There is no DMA in Quadra 800, so the CPU reads/writes the data from the
PDMA register (offset 0x100, ESP_PDMA in hw/m68k/q800.c) and copies them
to/from the memory.
There is a nice assembly loop in the kernel to do that, see
linux/drivers/scsi/mac_esp.c:MAC_ESP_PDMA_LOOP().
The start of the transfer is triggered by the DREQ interrupt (see linux
mac_esp_send_pdma_cmd()), the CPU polls on the IRQ flag to start the
transfer after a SCSI command has been sent (in Quadra 800 it goes
through the VIA2, the via2-irq line and the vIFR register)
The Macintosh hardware includes hardware handshaking to prevent the CPU
from reading invalid data or writing data faster than the peripheral
device can accept it.
This is the "blind mode", and from the doc:
"Approximate maximum SCSI transfer rates within a blocks are 1.4 MB per
second for blind transfers in the Macintosh II"

To prepare following patches move do_cmd and DMA special case
from handle_ti() to esp_do_dma().
This part of the code must be only executed with real DMA, not with
pseudo-DMA. And PDMA is detected in esp_do_dma(), so move this part
of the code in esp_do_dma(). We keep the code in handle_ti_cmd()
in the case no DMA is done.

Hoist the computation of some TBFLAG_A32 bits that only apply to
M-profile under a single test for ARM_FEATURE_M.

Create a function to compute the values of the TBFLAG_A32 bits
that will be cached, and are used by M-profile.

Set TBFLAG_ANY.BE_DATA in rebuild_hflags_common_32 and
rebuild_hflags_a64 instead of rebuild_hflags_common, where we do
not need to re-test is_a64() nor re-compute the various inputs.

Create a function to compute the values of the TBFLAG_A64 bits
that will be cached. For now, the env->hflags variable is not
used, and the results are fed back to cpu_get_tb_cpu_state.
Note that not all BTI related flags are cached, so we have to
test the BTI feature twice -- once for those bits moved out to
rebuild_hflags_a64 and once for those bits that remain in
cpu_get_tb_cpu_state.

The property names of AST2600 GPIO 1.8V model are one character bigger
than the names of the other ASPEED GPIO model. Increase the string
buffer size by one and be more strict on the expected pattern of the
property name.
This fixes the QOM test of the ast2600-evb machine under :
