arm: Remove zmx25 board and ARCH_MX25

This board has not been converted to CONFIG_DM by the deadline.
Remove it. As this is the last ARCH_MX25 platform, remove those
references as well.

Kconfig: Remove all default n/no options

default n/no doesn't need to be specified. It is default option anyway.

w1: Add driver for i.MX bus master controller

Two variants of controllers are supported:
V1 (bitwise only) found in
i.MX21, i.MX27, i.MX31, i.MX51
V2 (byte operations) found in
i.MX25, i.MX35, i.MX50, i.MX53

Only tested on i.MX53 hardware but in both modes
(by modifying the device tree).

w1: Add 1-Wire uclass

We might want to use 1-Wire devices connected on boards such as EEPROMs in
U-Boot.

Provide a framework to be able to do that.
