Currently arch specific headers can be included with
longer possible as there won't be a single mach anymore.
Move all stm32mp specific header files to include/mach/stm32mp/ to
prepare for multi-arch support.

Full buswidth for STM32MP131 means 2 byte wide, not 4 as the memory bus
is restricted to 16-bit. Teach barebox the difference.

There is nothing holding holding us back from reading SoC type in
the PBL. Migrate the necessary definitions to the header to allow
for this.

Revision A was 0x1000 and B was 0x2000, so I assumed the next would
be revision C valued 0x3000. Alas, it's revision Z with 0x2001...
Change the code accordingly and add detection for the new 800Mhz
profiles.
Code taken from U-Boot commit
cf0818b477 ("stm32mp1: support of STM32MP15x Rev.Z") and
Patch[1] "stm32mp1: add 800 MHz profile support".

The BSEC OTP holds information about SoC type and package.
The Tamp registers hold information from the BootROM about boot
source. Add support for both.
Additionally, the tamp registers can also hold a request from the
operating system about what mode to enter after boot, e.g.
boot-into-recovery. A global function is exported for this, but
unused so far.
