Subject: [PATCH v4 0/2] serial: 8250_dw: Add ACPI support for uart on Hisilicon Hip05 SoC

Handle all cases of dw8250_data->clk properly in dw8250_set_termios(), then
make it as the default set_termios callback for 8250 dw uart.

After that, add ACPI support for uart on Hisilicon Hip05 SoC, be careful that
it is not 16500 compatible, and with Heikki's patchset[1], we safely only add
ACPI identifier, due to the ACPI quirks in dw8250_quirks() only for "APMC0D08".

Change since v3:
- The new dev var patch is sent separately.
- Address the comment from Andy, and repost patches based on Heikki Krogerus's patchset[1]
  "[PATCHv2 0/3] serial: dw8250: ACPI tuning"  

Change since v2:
- Add a new patch to use new var dev in probe
- Use built-in device properties to set device parameters for existing device probed by acpi,
  suggested by Andy Shevchenko


Change since v1:
- Use acpi_match_device() instead of acpi_dev_found(), limit the check to the device
  being probed and not a global search for whole DSDT (pointed by graeme.gregory@...aro.org)
