9ea7519383 arm, imx6: add alternative PAD_CTL_DSE constants
Not all i.MX6 pads use the same drive strength table. So far only the
240 Ohm to 34 Ohm table was available. Because the constants used have
speaking names it can be confusing to use e.g. PAD_CTL_DSE_48ohm when
according to the reference manual 52 Ohm is the correct value. This
patch adds the 260 Ohm to 37 Ohm table.

For example, the IOMUXC_SW_PAD_CTL_PAD_SD2_CLK register (SD-card clock)
uses the added table.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

5ebf9ad96c arm,imx6: fix PAD_CTL_SPEED_LOW constant
For most i.MX6 processors the PAD_CTL_SPEED_LOW constant is the same.
Only the i.MX6 SoloLite is an exemption. So far the code did not
consider that. Additionally, for a few i.MX6 processors the code used
the wrong value for the constant.

This patch fixes the PAD_CTL_SPEED_LOW constant for:
 - i.MX6 Solo [1]
 - i.MX6 DualLite [1]
 - i.MX6 Dual [2]
 - i.MX6 Quad [2]
 - i.MX6 DualPlus [3]
 - i.MX6 QuadPlus [3]

Before, it was already correct for:
 - i.MX6 SoloLite [4]
 - i.MX6 SoloX [5]
 - i.MX6 UtraLite [6]
 - i.MX6 ULL [7]

290e7cfdbf mx6ull: Handle the CONFIG_MX6ULL cases correctly
Since commit 051ba9e082 ("Kconfig: mx6ull: Deselect MX6UL from
CONFIG_MX6ULL") CONFIG_MX6ULL does not select CONFIG_MX6UL anymore, so
take this into consideration in all the checks for CONFIG_MX6UL.

This fixes a boot regression.

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.
