Willy Tarreau e72e8bf1c9 floppy: split the base port from the register in I/O accesses
Currently we have architecture-specific fd_inb() and fd_outb() functions
or macros, taking just a port which is in fact made of a base address and
a register. The base address is FDC-specific and derived from the local or
global "fdc" variable through the FD_IOPORT macro used in the base address
calculation.

This change splits this by explicitly passing the FDC's base address and
the register separately to fd_outb() and fd_inb(). It affects the
following archs:
  - x86, alpha, mips, powerpc, parisc, arm, m68k:
    simple remap of port -> base+reg

  - sparc32: use of reg only, since the base address was already masked
    out and the FDC controller is known from a static struct.

  - sparc64: like x86 for PCI, like sparc32 for 82077

Some archs use inline functions and others macros. This was not
unified in order to minimize the number of changes to review. For the
same reason checkpatch still spews a few warnings about things that
were already there before.

The parisc still uses hard-coded register values and could be cleaned up
by taking the register definitions.

The sparc per-controller inb/outb functions could further be refined
to explicitly take an FDC register instead of a port in argument but it
was not needed yet and may be cleaned later.
