Merge the PC98 fdc(4) driver into the MI driver. While here, replace
the magic numbers used with NE7CMD_SPECIFY with invocations of the
NE7_SPEC_x() macros.

Reimplement the FDOPT_NOERROR feature that was kicked out in r134081.

It is needed for fdread(1) in order to be able to recover from CRC
errors in the data field of a floppy sector (by returning the sector
data that failed CRC, rather than inventing dummy data).

When closing the device, clear all transient device options.

Do not use "Enable Implied Seek" on enhanced floppy controllers. This
breaks the "2step" feature of the driver, e.g. in order to read 360
KiB media on a 1200 KiB drive.

Do not use "Enable Implied Seek" on enhanced floppy controllers. This
breaks the "2step" feature of the driver, e.g. in order to read 360
KiB media on a 1200 KiB drive.

As the only potential advantage of implied (vs. explicit) seeks is to
minimize the software effort, yet our driver always contained the
logic needed for explicit seeks, simply dropping implied seeks is the
best solution without introducing risks for new bugs. There is no
performance penalty, reading a 1440 KiB medium takes exactly the same
time with both, implied or explicit seeks.

Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.

The SYSCTL_NODE macro defines a list that stores all child-elements of
