552a848e4f imx: reorganize IMX code as other SOCs
Change is consistent with other SOCs and it is in preparation
for adding SOMs. SOC's related files are moved from cpu/ to
mach-imx/<SOC>.

This change is also coherent with the structure in kernel.

DM FEC and SPI are not enabled, but they use gpio in board code.
So use gpio_request first to request the gpio, because DM_GPIO

edf0093732 mx6: ddr: Allow changing REFSEL and REFR fields
Currently MX6 SPL DDR initialization hardcodes the REF_SEL and
REFR fields of the MDREF register as 1 and 7, respectively for
DDR3 and 0 and 3 for LPDDR2.

Looking at the MDREF initialization done via DCD we see that
boards do need to initialize these fields differently:

$ git grep 0x021b0020 board/

So introduce a mechanism for users to be able to configure
REFSEL and REFR fields as needed.

Keep all the mx6 SPL users in their current REF_SEL and REFR values,
so no functional changes for the existing users.

155fa9af95 spi: mxc: fix sf probe when using mxc_spi
MXC SPI driver has a feature whereas a GPIO line can be used to force CS high
across multiple transactions. This is set up by embedding the GPIO information
in the CS value:

cs = (cs | gpio << 8)

This merge of cs and gpio data into one value breaks the sf probe command:
if the use of gpio is required, invoking "sf probe <cs>" will not work, because
the CS argument doesn't have the GPIO information in it. Instead, the user must
use "sf probe <cs | gpio << 8>". For example, if bank 2 gpio 30 is used to force
cs high on cs 0, bus 0, then instead of typing "sf probe 0" the user now must
type "sf probe 15872".

This is inconsistent with the description of the sf probe command, and forces
the user to be aware of implementaiton details.

Fix this by introducing a new board function: board_spi_cs_gpio(), which will
accept a naked CS value, and provide the driver with the relevant GPIO, if one
is necessary.

The additional fields of iomuxc_base_regs are not used. Other advantage of
'iomuxc' is that it has a shorter name and the variable declarations can fit
into a single line.

So remove iomuxc_base_regs structure and use iomuxc instead.

7e2173cf82 imx: iomux-v3: Include PKE and PUE to pad control pull definitions
PUE requires PKE to mean something, as do pull values with PUE, so do not
compell users to explicitly use PKE and PUE everywhere. This is also what is
done on Linux and what has already been done for i.MX51.

By the way, remove some unused pad control definitions.

There is no change of behavior.

Note that SPI_PAD_CTRL was defined by several boards with a pull value, but
without PKE or PUE, which means that no pull was actually enabled in the pad.
This might be a bug in those boards, but this patch does not change the
behavior, so it just removes the meaningless pull value from those definitions.
