Corrected typo in legacy PCA82C200 (SJA1000 std) chip driver.
Thanks to Terence Soh for noticing the problem.
Important notice, if the board is equipped by real SJA1000
CAN controller chip, then PeliCAN mode is much much better
choice and sja1000p_register() function should be used
instead of bare standard sja1000_register() chip support.

Changes in CAN/PCI-200 card sources to be more clean in types
The newer kernels are very picky about diferentiate of numbers,
virtual and IO afddresses types. Try to follow rules and allow
compatability with older kernels is little csardas.

Minor correction in PEAK PCI can support.
Some first tests worked on DigitalLogic's MSMCA104+
card clone. But interrupt handling requires
more testing. PITA documentation is unclear and real
behavior of IRQ status has to be analyzed and code
has to be adjusted accordingly.

The first round of I/O space pointers separation.
The new 2.6.x Linux kernels separates I/O space
addresses from kernel and user space ones.
They are defined as (void __iomem *).
To follow this rule and suppress some warnings
LinCAN defines type can_ioptr_t now which allows
to keep code compatible between 2.4.x and 2.6.x kernels.
These changes exposes more other inconsistencies
in some boards support code which should be corrected
one by one later.
The code requires testing and checking on more hardware.

Deep rewrite of TSCAN1 and TS7KV boards support.
Result requires tests on real hardware and probability
of breakage is very likely. The main aim of the rewrite
is to simplify register access code. The LinCAN driver
does not require more than first 32 byte ports to control
SJA1000 in pelican mode. With this simplification, no windowing
is required for TSCAN1 and only minimal support for access
of SJACDR has been left for TS7KV. The boards lookup checks
for IO range availability and TSCAN1 window can be placed
automatically as well. The "canio" parameter changed to "tscanio".

SJA1000 driver interrupts processing modified to not rely on interrupt register for Rx and Tx.
The information about free chip ready condition for Tx message is now
obtained from status register. This solution enables us to equip SJA1000
driver by irq_accept method. Then only this part has to be run in real IRQ
handler and rest of ISR can be done in other thread. This is required
for possible porting to QNX as well. Change should helps to better
