Patch from Vincent Sanders
When building the mx1ads ARM platforms the serial driver fails to compile
with GCC 4.01 due to extern/static ambiguity.

This change removes a bogus error message from the IOC4 serial driver
interrupt handler.
This error message is bogus for two reasons. First, it can never occur
given that current code takes care to initialize IOC4 in such a way that
these "unknown" interrupts could never occur. Second, this code fails to
take into account that other drivers can share the IOC4 interrupt mechanism
through SA_SHIRQ, and thus this driver is not in-fact "all-knowing".
Finally, this error message triggers every time some "unknown" interrupt
occurs -- it's not rate limited or repetition limited in any way, thereby
effectively denying use of the console device. Given its bogosity in the
first place, it's best to just get rid of it entirely.

It's pointless to include mach-types.h if you're not going to use

m8xx_cpm_hostalloc() can't rely on using the coherent DMA allocator early
on boot because the VM is not fully up yet. Change it to use the on-board
DPRAM instead.
The current code relies on the "bootmem_page" allocated by
m8xx_cpm_reset(), which must be killed.
This is done in v2.4 but has never been forward ported to v2.6.

Add support for the MRi PCIDS1 dual port serial card. This card is a
little controversial since it is the subject of a PCI vendor/device ID
clash. (See
http://www.ussg.iu.edu/hypermail/linux/kernel/0303.1/0516.html). I have
for now just used the hex ID 0x950a. The divisor was part calculated part
iterated, so may not be exactly correct (but works for me at all settings
between 300 - 115300 bps).
