asm/serial.h is supposed to contain the definitions for the architecture
specific 8250 ports for the 8250 driver. It may also define BASE_BAUD,
but this is the base baud for the architecture specific ports _only_.
Therefore, nothing other than the 8250 driver should be including this
header file. In order to move towards this goal, here is a patch which
removes some of the more obvious incorrect includes of the file.

The patch below is necessary for 115200 baud on an OMAP1510 internal UART.
It's been in the linux-omap tree for some time and with it applied to a
vanilla Linus git tree the serial console on the Amstrad Delta (which is
OMAP1510 based and whose initial bootloader runs at 115200) works fine (it
doesn't without it).

Fix the issue of returning 0 even in case of error from uart_set_info
function. Now it returns the error EBUSY when it can not set new port.

/proc/tty/driver/serial incorrectly claims that UARTs having iotype of
UPIO_MEM32, UPIO_AU, or UPIO_TSI are I/O mapped.

8250.c and serial_txx9.c port suspend/resume handler still have this obsolete

I think register ranges obviously need to be claimed/released for all UARTs
including those with UPIO_MEM32 and UPIO_TSI iotype.
Also, serial8250_request_rsa_resources() returns false positives with
UPIO_MEM32, UPIO_AU, and UPIO_TSI iotype -- I don't think this makes any sense.

Mauro Ziliani reports that this card has a higher clock rate.
Rather than tweak the 8250 driver to handle this, add a quirk to
pass the correct clock rate to the driver.

According to the existing code, Nokia only make single-port cards,
but are detected as multi-port cards. Handle this in roughly the
same way via the config quirk - forcing it to be a real single port
card (info->multi=0) changes the way we allocate the IO memory,
which might stop the card working.

Add a quirk primerily to handle tweaks to the link->conf structure,
eg as required for Socket cards.

Move IBM quirk handling into its own quirk entry. Note that doing
quirk handling after we've registered the ports is racy, but since
I don't know if moving this will have an undesired effect, it's
probably better to leave where it is.

Some quirks we will introduce next apply to (eg) all cards of one
manufacturer. Therefore, we need a way to list these in the quirk
table - use ~0 - this is not a possible device ID value.

- rename multi_id table to serial_quirk / quirks[]
- use named initialisers
- store a pointer to the quirk table in the serial_info structure
so we can use the quirk table entry later.
- apply multi-port quirk after the multi-port guessing code,
but only if it's != -1.

- Use ARRAY_SIZE() instead of home grown based version.
- use parse->manfid.card rather than le16_to_cpu(buf[1]) -
manfid.card is already converted to this format.
- use info->prodid in subsequent tests rather than
parse->manfid.card.

m32r_sio re-uses a custom defined BASE_BAUD from asm/serial.h,
and replaces SERIAL_PORT_DFNS with its own driver private copy.
Since asm/serial.h is supposed to define 8250-based ports using
these symbols, this isn't a sane idea.
Hence, eliminate asm/serial.h from m32r_sio.c.
