Patch removes optional "ptp" clock source for FEC. This clock is
missing in i.MX27.

Add a label to i.MX27 CPU node. This change allows the reuse this node
in the upper levels of the DTS.

i.MX27 CPU can be clocked with a 32 kHz quartz, and not just 32768 Hz,
so increase "clock-latency" value, which will ensure that we use two
clock cycles on frequency change.

Outputs regulator SW1A and SW1A, SW2A and SW2B are connected together,
so it determined as "joined" operation for MC13783. Separate work of
these outputs in this case would be wrong, so we define only one of
the outputs.
Additionally, define the full range of voltages for the CPU (1.2v - 1.52v).
