Since sci_rxd_in() is used by SCI only, clean up
the header file by killing off code dealing with
SCIF ports and their register definitions.

Also introduce a default sci_rxd_in() function
which can be shared by all SCIF-only processors.

Perform a tricky suspend/resume even with no_console_suspend.

With no_console_suspend, kernel skips serial port suspend/resume and the
serial hardware may remain in undefined state after resume. It actually
happens on devices that don't have BIOS that handle serial
initialization. It makes impossible to use serial console after resume.

Devices affected by this problem include:
Sharp Zaurus devices
Several PXA based ARM embedded boards

The patch does:
- Save the hardware state
- Perform buffer flush in time of its suspend call
- Tell the driver that port is suspended
- But still accept new data
- And keep console hardware in state that allows to send them

It allows to capture late console messages without breaking console
after resume.

This is just a resend of a patch discussed in these threads, as the
patch was not yet applied.

Intel(R) PXA27x Processor Family Specification Update (Nov 2005)
says:

  E75. UART: Baud rate may not be programmed correctly on
       back-to-back writes.

  Problem:
  When programming the Divisor Latch registers, Low and High (DLL and
  DLH), with back-to-back writes, the second register write may not
  take effect. The result is an incorrect baud rate.

  Workaround:
  After programming the first Divisor Latch register, read and verify
  it before programming the second Divisor Latch register.

This was hit when changing the baud rate from 115200 to 9600 while
receiving characters at 9600 Bd.

Unfortunately, one cannot hold on to the struct firmware
that request_firmware_nowait() hands off, which is needed
in some cases. Allow this by requiring the callback to
free it (via release_firmware).

Additionally, give it a gfp_t parameter -- all the current
users call it from a GFP_KERNEL context so the GFP_ATOMIC
isn't necessary. This also marks an API break which is
useful in a sense, although that is obviously not the
primary purpose of this change.

Currently serial ports on SH CPUs get disabled too early, because the
sci_tx_empty() routine claims to not be able to detect whether the
transmission has been completed and just always returns TIOCSER_TEMT. This
results in corrupt output of last characters if the port is not open for
reading at the same time. It is however possible to detect whether
transmission has been completed. Use the TEND bit of the status register
for this.

Most of the irq_req_t typedef'd struct can be re-worked quite
easily:

(1) IRQInfo2 was unused in any case, so drop it.

(2) IRQInfo1 was used write-only, so drop it.

(3) Instance (private data to be passed to the IRQ handler):
	Most PCMCIA drivers using pcmcia_request_irq() to actually
	register an IRQ handler set the "dev_id" to the same pointer
	as the "priv" pointer in struct pcmcia_device. Modify the two
	exceptions (ipwireless, ibmtr_cs) to also work this waym and
	set the IRQ handler's "dev_id" to p_dev->priv unconditionally.

(4) Handler is to be of type irq_handler_t.

(5) Handler != NULL already tells whether an IRQ handler is present.
	Therefore, we do not need the IRQ_HANDLER_PRESENT flag in
	irq_req_t.Attributes.
