Re-commit Exar XR17V35x serial port support previously backed out:

The Exar XR17V354 has 4 ports that have a 256-byte FIFO, use a
frequency of 125Mhz, and have a unique sleep register. A custom
interrupt handler is setup in puc for these ports so it can check a
register which reports which ports triggered the interrupt, rather
than having to run comintr for every port every time.

To avoid probing for these ports in com_attach_subr which requires
access to registers that may be reserved on certain platforms, pass
the sc_uarttype from com_puc_attach since the port type is already
known based on the puc device vendor/id.

Input from kettenis, tested in snaps

Add support for register shift/io-width to the console code as well.

Revert previous commit; the XR17V35X probe that was added accesses registers
that aren't guaranteed to be there and may even belong to a different device.
This triggers a fault on hppa machines like the C3000 for example.

Add support for register shift/io-width. This allows us to support UARTs
that are mostly NS16550 compatible but use 32-bit instead of 8-bit registers
such as the Synopsys Designware UARTs found on many armv7, arm64 and amd64
SoCs.

Make serial console on non-primary ports work to on i386.

tested by jbg@, "it is right" deraadt@

fix serial console handling on amd64. currently only glass console ever
works, even if the boot loader is configured to use serial console.

after the changes jsing and i made, the initial probe of the serial port
was failing since the default base addres for the port is invalid. cos of
that the kernel would only ever consider the glass console for use. this
fixes it by reprobing the serial port if we get any config for it from the
boot loader.

Add support for register shift/io-width. This allows us to support UARTs
that are mostly NS16550 compatible but use 32-bit instead of 8-bit registers
such as the Synopsys Designware UARTs found on many armv7, arm64 and amd64
SoCs.

Make serial console on non-primary ports work to on i386.

tested by jbg@, "it is right" deraadt@

fix serial console handling on amd64. currently only glass console ever
works, even if the boot loader is configured to use serial console.

after the changes jsing and i made, the initial probe of the serial port
was failing since the default base addres for the port is invalid. cos of
that the kernel would only ever consider the glass console for use. this
fixes it by reprobing the serial port if we get any config for it from the
boot loader.

- Merge changes from pxacom back into the common com driver.

Changes to the common com driver (partly from NetBSD):
- Multiply before divide in comspeed() to avoid overflow (from NetBSD).
- Don't call getc() and send -1 if the output queue is empty.
- Take UART clock frequency as a parameter instead of using COM_FREQ.

Replace select backends with poll backends. selscan() and pollscan()

- support for generic soft interrupts.

Split out comattach that does isa and isapnp attachment and initialization,

Revert previous commit; the XR17V35X probe that was added accesses registers
that aren't guaranteed to be there and may even belong to a different device.
This triggers a fault on hppa machines like the C3000 for example.

The Exar XR17V354 has 4 com ports that have a 256-byte FIFO, use a
frequency of 125Mhz, and have a unique sleep register. A custom
interrupt handler is setup in puc for these ports so it can check a
register which reports which ports triggered the interrupt, rather
than having to run comintr for every port every time.
