Improve the bindings text by doing the following changes:
- Remove the i.MX53 reference, as the RTC on i.MX53 is a different hardware
- Add 'clocks' to the list of required properties
- Explain that the optional security violation irq is the second entry
- Use the real unit address and irq numbers for i.MX25

The Armada 7K/8K use the same RTC IP than the Armada 38x. However the SOC
integration differs in 2 points:
- MBUS bridge timing initialization
- IRQ configuration at SoC level
Moreover the Armada 7K/8K have an issue preventing to get the interrupt
from alarm 1. This commit allows to use alarm 2 for these A7K/8K but to
still use alarm 1 for the Armada 38x.

There are currently two broken bindings descriptions for RTC:
maxim,ds3231.txt
pcf8563.txt
They broke because of a improper RST documentation conversion with
commit 8c27ceff3604b2 ("docs: fix locations of several documents that got
moved") and now reference to a non-existing file:
Documentation/devicetree/bindings/i2c/trivial-admin-guide/devices.rst
However, the original reference to i2c/trivial-devices should have never
been made in the first place.
This change fixes this issue by replacing with correct descriptions.

The RTC controls the input source of the main 32kHz oscillator in the
system, feeding it to the clock unit too.
By default, this is using an internal, very inaccurate (+/- 30%)
oscillator with a divider to make it roughly around 32kHz. This is however
quite impractical for the RTC, since our time will not be tracked properly.
Since this oscillator is an input of the main clock unit, and since that
clock unit will be probed using CLK_OF_DECLARE, we have to use it as well,
leading to a two stage probe: one to enable the clock, the other one to
enable the RTC.
There is also a slight change in the binding that is required (and should
have been from the beginning), since we'll need a phandle to the external
oscillator used on that board. We support the old binding by not allowing
to switch to the external oscillator and only using the internal one (which
was the previous behaviour) in the case where we're missing that phandle.
