The Sony drive status bits use active-low logic. The swim_readbit() function converts that to 'C' logic for readability. Hence, the sense of the names of the status bit macros should not be inverted. Mostly they are correct. However, the TWOMEG_DRIVE, MFM_MODE and TWOMEG_MEDIA macros have inverted sense (like MkLinux). Fix this inconsistency and make the following patches less confusing. The same problem affects swim3.c so fix that too. No functional change. The FDHD drive status bits are documented in sonydriv.cpp from MAME and in swimiii.h from MkLinux.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
