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.

Add a separate function call for imx8mp_early_clock_init, to avoid
confusion with imx8mm.

PBL runs fine when doing the same early clock setup as for the i.MX8MM:
i2c communication works, copying to DRAM works, but boot hangs in
barebox proper. Vendor patches for U-Boot configure SYS_PLL3 as 600MHz
for i.MX8MP and i.MX8MN. barebox i.MX8MP port evidently can do without,
but for i.MX8MN, reducing PLL frequency to 600MHz was required to boot.

The i.MX8M boards all have the same code for setting up the UART clock.
Add a common helper for it. In the helper just setup the clocks for all
UARTs as it's not worth it to have separate functions for each UART.

U-Boot has some lowlevel clock functions which take a clock slice index
as argument. Add them for barebox as well to make the code better
comparable to U-Boot.

i.MX8 is something different than the i.MX8M and both will not share
this header file, so rename it to imx8m-ccm-regs.h
