srd: Rename onewire_transport to maxim_ds28ea00.

It doesn't make sense to have one "generic" onewire_transport PD, as
this layer is very much device-specific and such a generic PD would
have to contain an accumulation of all possible features and commands
and handling code of all existing (now and in the future) 1-Wire
devices, which is neither possible nor useful nor elegant.

There are (for example) 1-Wire thermometers, RTCs, EEPROMs,
special-purpose security chips with passwords/keys, battery monitoring
chips, and many many others. They all have a different set of features,
commands and command codes, RAM areas/sizes/partitioning/contents,
protocols, and so on.

Thus, the layering for 1-Wire PD stacks should look like this:

 onewire_link -> onewire_network -> <specificdevice>

Examples:

 onewire_link -> onewire_network -> maxim_ds28ea00 (special thermometer)
 onewire_link -> onewire_network -> maxim_ds2431 (1kbit EEPROM)
 onewire_link -> onewire_network -> maxim_ds2417 (RTC)
 onewire_link -> onewire_network -> maxim_ds2762 (battery monitor)
 onewire_link -> onewire_network -> maxim_ds1961s (SHA-1 eCash iButton)
 and so on...

So, renaming onewire_transport to maxim_ds28ea00. The non-DS28EA00
specific code will be dropped and/or moved to other PDs on top of
onewire_network later.

-1-Wire protocol decoder.
-
-The 1-Wire protocol enables bidirectional communication over a single wire (and
-ground) between a single master and one or multiple slaves. The protocol is
-layered.
-- Link layer (reset, presence detection, reading/writing bits)
-- Network layer (skip/search/match device ROM addresses)
-- Transport layer (transport data between 1-Wire master and device)
-
-Transport layer
-
-The transport layer is the largest and most complex part of the protocol, since
-it is very device specific. The decoder is parsing only a small part of the
-protocol.
-
-Annotations:
-The next link layer annotations are shown:
-- RESET/PRESENCE True/False
-  The event is marked from the signal negative edge to the end of the reset
-  high period. It is also reported if there are any devices attached to the
-  bus.
-The next network layer annotations are shown:
-- ROM val
-  The 64bit value of the addressed device is displayed:
-  family code (1B) + serial number (6B) + CRC (1B)
-- FUNCTION COMMAND val name
-  The requested FUNCTION command is displayed as an 8bit HEX value and by name.
-- DATA val
-  Data intended for the transport layer is displayed as an 8bit HEX value.
-
-TODO:
-- add CRC checks for transport layer
