On mpc832x, SPI can be either handled by CPU or QE.
In order to work in CPU mode, bit 17 of SPMODE has to
be set to 1, that bit is called OP.
Also, data is located at a different place than the one expected
by the driver today. In 8 bits mode with REV set, data to be
transmitted is located in the most significant byte while
received data is located in second byte. So perform the
necessary shifts.
In order to differentiate with other CPUs, a new compatible is
added for mpc832x: fsl,mpc832x-spi

The mpc832x has GPIOs handled by the QUICC Engine.
The registers are different from the one for the
non QE mpc83xx GPIOs.
Implement a GPIO driver for those.

At startup, some RAM is needed (for instance for stack) before
DRAM is initialised.
One way to offer such RAM, used by mpc83xx, is to lock some entries
in the cache. To do that, MMU needs to be activated.
On mpc83xx having a QUICC Engine an alternative is to user some
part of from the Multi User RAM, like done on mpc8xx for instance.
For that, the MMU is not needed.
Activating the MMU is problematic because exception vectors are not
setup yet so in case of ISI or DSI that CPU will crash and reboot.
At the time being, MMU is activated regardless.
Only activate it when locking cache entries to provide initial RAM.

mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same

Refactor the driver to get the register addresses from the
device tree and use the compatible to know the prescale factor.
Calculate the watchdog setup value from the provided timeout.
Don't declare it anymore as an HW_WATCHDOG, u-boot will start
servicing the watchdog early enough.
On mpc8xx the watchdog configuration register is also used for
configuring the bus monitor. So add it as an option to the watchdog
when it is mpc8xx. When watchdog is not selected, leave the
configuration of the initial SYPCR from Kconfig.

The DWMAC clock in i.MX8M Plus were so far configured via ad-hoc
architecture code. Replace that with DM clock instead. This way,
the driver claims all its required clock, enables and disables
them, and even gets the CSR clock rate and sets the TX clock rate,
without any need of architecture specific register fiddling. Drop
the architecture specific code while at it too.
The adjustment here is modeled after STM32MP15xx clock handling

the upstream version does not have it.
This causes a boot regression in which the eMMC card cannot be found anymore.
