Depending on the application, board code might want to configure
different power levels and brownout thresholds. They can do so now with
an additional struct mxs_power_ctrls* parameter to mx2*_power_init.

Note that VDDMEM was not set up explicitely in mx28_power_init, but can
now be configured. However, mx28_power_default->vddmem is NULL, so the
old behaviour is still the case when using those default values.

Having three ints as parameter suggests that we can use up to 2^3
power configurations for the system, but when we look at the code, the
power setup is packaged in if {...} else if {...} else if {...} blocks,
so setting more than one parameter to 1 is useless here.

Refactor the parameters into an enum to get rid of that suggestion.

Allow to set not only the fractional divider, but also the prescaler for
the EMI clock in mxs_mem_init_clock(), and rename the parameters
accordingly to reflect the change. Port the existing board code to set
up the EMI clock explicitely with the old values. Also fix the
off-by-a-half error in the comments, which did not take the prescaler of
2 into account, on which the fractional divider is applied (according to
the i.MX23/i.MX28 Reference Manuals)

Commit 4d70da6 ("ARM: MXS: power-init: Add parameters to
mx28_power_init()") causes imx233-olinuxino to not boot anymore.

imx233-olinuxino is commonly powered from external input supply,
so adjust the mx23_power_init() arguments to reflect that.

Instead of introducing new functions each time a new power supply
situation is to be added, this patch adds parameters to mx28_power_init.

Right now there are three parameters:

- has_battery - true when this board has a battery.
- use_battery_input - true when this board is supplied from the
  battery input, but has a DC source instead of a real battery
- use_5v_input - true when this board can use the 5V input

The third one is introduced with this patch and allow to boot a board from 5v
(USB) source only. The main necessary change this needs is that the DC-DC
converter must always be sourced from DCDC_4P2 (DROPOUT_CTRL field of
HW_POWER_DCDC4P2)
