In RCM aka recovery mode the BootROM waits for a
usbloader to take over control. On most boards this
is triggered by holding a physical switch which may
be inconvinient at times. Add a command to switch
into RCM from software.

The voltage for programming the fuses is external to the SoC and
on some boards this is controllable with a regulator, so add regulator
support to the iim driver.

With devicetree devicenames start with numbers. Parameters on these
devices are not accessible since variables can't start with numbers.
Register a logical 'iim' device which makes the permanent_write_enable
and explicit_sense_enable parameters accessible again.

Bit 7 of UCR3 is described in the i.MX reference manuals (with the exception
of i.MX1) as follows:
ADNIMP: Autobaud Detection Not Improved-. Disables new features of
autobaud detection (See Baud Rate Automatic Detection
Protocol, for more details).
0 Autobaud detection new features selected
1 Keep old autobaud detection mechanism
The "new features" mechanism occasionally causes the receiver to get out of sync
and continuously produces received characters of '0xff'.
In order to reproduce the problem:
$ cs0.baudrate=19200
- Change the terminal baudrate to 19200
- Type in the console and it should look good
- Change the terminal baudrate back to 115200
- Type 'b' in the console, then a stream of '0xff' is transmitted in loop
Setting the ADNIMP bit avoids the transmission of '0xff' in loop.
Also rename the bit definition as per the reference manual.
Tested on mx6q.

This patch reduces the indentation of "devinfo", to reduce the amount of
overly long lines.
And while we're at it, also remove the fixed-size of the human-readable
area. As entries didn't align anyway (because of indentation), this was
just eating more space without giving much more readability.

* some output sections started with "foo: bar", some with "foo = bar". Unify this.
* there was a fixed size to the "foo =" parameters, which wasn't fitting, this
was especially visible at "devinfo global"
* don't output "resources:", "driver:" and "bus:" lines if there are none
resources, drivers or busses involved.
