ARM: dts: imx35: restore existing used clock enumeration

commit 3397c2c45b1b6f54834dfeae30a73046f33ca943 upstream.

A new element got inserted into enum mx35_clks with commit 3713e3f5e927
("clk: imx35: define two clocks for rtc"). This insertion shifted most
nummerical clock assignments to a new nummerical value which in turn
rendered most hardcoded nummeric values in imx35.dtsi incorrect.

Restore the existing order by moving the newly introduced clock to the
end of the enum. Update the dts documentation accordingly.
