3397c2c45b ARM: dts: imx35: restore existing used clock enumeration
A new element got inserted into enum mx35_clks with commit 3713e3f5e9
("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.

57d5a4c3ed clk: imx35: retain early UART clocks during kernel init
Make sure to keep UART clocks enabled during kernel init if
earlyprintk or earlycon are active.

8d449cb5e2 clk: imx35: Do not call mxc_timer_init twice when booting with DT
mxc_timer_init must not be called from within mx35_clocks_init_dt. It will
eventually be called by imx31_timer_init_dt
(drivers/clocksource/timer-imx-gpt.c).
This arranges the initialization code similar to clk-imx27.c

3713e3f5e9 clk: imx35: define two clocks for rtc
The imx35 don't define clocks for rtc.
This patch add two clocks, as needed
by the mxc rtc driver.

0931aff722 ARM: imx: define an enum for gpt timer device type
Define an enum for gpt timer device type in include/soc/imx/timer.h to
tell the gpt block differences among SoCs.  Update non-DT users (clock
drivers) to pass the device type.

As we now have include/soc/imx/timer.h, the declaration of
mxc_timer_init() is moved into there as the best fit.

de8e434d09 ARM: imx: drop epit timer initialization from imx35 clock driver
EPIT provides another timer implementation besides the default GPT
timer.  The imx35 clock driver will use EPIT timer when option
CONFIG_MXC_USE_EPIT is enabled.  However, initializing timers from
clock driver is a workaround solution and causes problem when we move
clock drivers into driver/clk.

Let's simply drop the EPIT initialization from there.  If people really
want this EPIT option, EPIT timer driver needs to be reworked to do the
initialization in a standard way - use CLOCKSOURCE_OF_DECLARE() with
device tree support.

11f6812009 ARM: imx: move clock drivers into drivers/clk
After the cleanup on clock drivers, they are now ready to be moved into
drivers/clk.  Let's move them into drivers/clk/imx folder.
