Fix several issues with the driver's procfs output:
- when testing if channel is enabled, the code looks at the "simplex" bits, not
at the real enable bits -- add #define for the primary channel enable bit;
- UltraDMA modes 0, 1, 3 for slave drive reported incorrectly due to using the
master drive's clock cycle resolution bit.
While at it, also perform the following cleanups:
- don't print extra newline before the first controller's dump;
- correct the chipset names (from CMDxxx to PCI-xxx)
- don't read from the registers which aren't used for dump;
- better align the table column sizes;
- rework UltraDMA mode dump code;
- remove PIO mode dump code that has never been finished;
- remove the duplicate interrupt status (the MRDMODE register bits mirror those
those in the CFR and ARTTIM23 registers) and fold the dump into single line;
- correct the style of the ?: operators...
