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".

Added more detailed SJA1000 error reporting and primitive report rate limiting.
The detailed SJA1000 error reporting is enabled by adding next line

Ronald Gomes from Technologic Systemscontributed support for TS-CAN1 and TS-7KV cards.
This is initial version and would require more cleanups and optimizations.

LinCAN driver updated to work on Real-Time Preemption enabled kernel.

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
recover form bus-off mode as well.

Fixed bug message objects indexing introduced by previous driver changes.
This indicates, that i82527 requires more testing after 0.3.x driver

More updates in the C_CAN support, but locking not reworked still.
The filters setup should work this time. But separation of CCIF1
only from IRQ and CCIF2 from other places and locking not redone yet.

Added attach_to_chip() and release_chip() functions for each chip.
This enables correct stopping and IRQ disable before driver unload.
This is required to get rid of problematic handling of shut down

The MAX_MSGOBJS limit increased to 32 due to requirements of C_CAN chip.
This wastes 68-124 bytes for other chips. Some better solution should be

Changes, which should enable to handle more VME Unican cards under RT-Linux.
Solution is not fully clean and it is not consistent with RT-Linux
way to handle regular ISA and PCI interrupts. The deeper analysis is
required, how to use this approach with regular Linux. May it be, that Linux 2.6.x
with latest IRQ threads and mutexes instead of spin-lock patches from Ingo
Molnar could profit from this in future too.

Changed baudrate calculation to consider DSC selection.
This affects only PIPx cards, because only these use
crystal <10MHz (8 MHz in the case) and i82527 chip.
