drivers/parport: Group adapter commands

Use a command group 'parport' with subcommands instead of individual
commands with 'parport_' prefix.

The old commands are still available for backward compatibility but
marked as deprecated.

connected to a PC's EPP mode parallel port.
This defines some driver-specific commands:
@deffn {Config Command} {parport_port} number
@deffn {Config Command} {parport port} number
Specifies either the address of the I/O port (default: 0x378 for LPT1) or
the number of the @file{/dev/parport} device.

These interfaces have several commands, used to configure the driver

@deffn {Config Command} {parport cable} name
Set the layout of the parallel port cable used to connect to the target.

When using PPDEV to access the parallel port, use the number of the parallel port:
@option{parport_port 0} (the default). If @option{parport_port 0x378} is specified
@option{parport port 0} (the default). If @option{parport port 0x378} is specified

To measure the toggling time with a logic analyzer or a digital storage

> adapter speed 500
