target/arm: Fix accidental write to TCG constant
Currently an unpredictable movw such as
movw pc, 0x123
results in the tinycode
and_i32 $0x123,$0x123,$0xfffffffc
mov_i32 pc,$0x123
exit_tb $0x0
which is clearly a bug: writing to a constant is incorrect and
discards the result of the mask. Fix this by always doing an and_i32
and trusting the optimizer to turn this into a simple move when the
mask is zero.

hw/display/xlnx_dp.c: Don't abort on AUX FIFO overrun/underrun
The documentation of the Xilinx DisplayPort subsystem at
https://www.xilinx.com/support/documents/ip_documentation/v_dp_txss1/v3_1/pg299-v-dp-txss1.pdf
doesn't say what happens if a guest tries to issue an AUX write
command with a length greater than the amount of data in the AUX
write FIFO, or tries to write more data to the write FIFO than it can
hold, or issues multiple commands that put data into the AUX read
FIFO without reading it such that it overflows.
Currently QEMU will abort() in these guest-error situations, either
in xlnx_dp.c itself or in the fifo8 code. Make these cases all be
logged as guest errors instead. We choose to ignore the new data on
overflow, and return 0 on underflow. This is in line with how we handled
the "read from empty RX FIFO" case in commit a09ef5040477.

hw/display/xlnx_dp: Don't abort for unsupported graphics formats
If the guest writes an invalid or unsupported value to the
AV_BUF_FORMAT register, currently we abort(). Instead, log this as
either a guest error or an unimplemented error and continue.
The existing code treats DP_NL_VID_CB_Y0_CR_Y1 as x8b8g8r8
via a "case 0" that does not use the enum constant name for some
reason; we leave that alone beyond adding a comment about the
weird code.
Documentation of this register seems to be at:
https://docs.amd.com/r/en-US/ug1087-zynq-ultrascale-registers/AV_BUF_FORMAT-DISPLAY_PORT-Register

hw/audio/lm4549: Don't try to open a zero-frequency audio voice
If the guest incorrectly programs the lm4549 audio chip with a zero
frequency, we will pass this to AUD_open_out(), which will complain:
A bug was just triggered in AUD_open_out
Save all your work and restart without audio
I am sorry
Context:
audio: frequency=0 nchannels=2 fmt=S16 endianness=little
The datasheet doesn't say what we should do here, only that the valid
range for the freqency is 4000 to 48000 Hz; we choose to log the
guest error and ignore an attempt to change the DAC rate to something
outside the valid range.
