Currently arch specific headers can be included with #include <mach/xxx.h>.
With upcoming multi-arch support this is no longer possible as there
won't be a single mach anymore.
Move all i.MX specific header files to include/mach/imx/ to prepare for
multi-arch support.

imx7_early_setup_uart_clock() has a very generic sounding name, but so
far only set up clocks for UART1. This can lead board code authors
astray that intend to user a different UART for DEBUG_LL.
This issue affects board code for kamstrup-mx7-concentrator, meerkat96
and zii-imx7d-dev, which use UART4, UART6 and UART2 respectively.
As I don't have this boards available to test and clock changes may have
adverse effect elsewhere, we have all existing users setup UART1 as
before, but note with a comment that this may not be the original
author's intention.

The i.MX7 boards have the same code for setting up the UART clock. Add a
common helper function for it.

The CCM defines used on i.MX7 and i.MX8M do not have any SoC namespace.
Add it to make clear where they are supposed to be used. Since it looks
confusing to call i.MX7 specific defines on i.MX8M and vice versa,
duplicate them for both SoCs.

The name mx7_setup_pad already implies the SoC where it runs on, so we
do not have to pass the iomux base address but can hardcode it in the
function. While at it rename it to imx7_setup_pad() which is more
consistent to other i.MX specific functions.

To prepare for addition of another ZII i.MX7D based board, i.MX7D
RMU2, rename zii-imx7d-rpu2 to zii-imx7d-dev to avoid any image naming
confusion.
