As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d, reversing
changes made to 2ee6f3a5f7.

When using OF_LIVE, the debug UART driver won't be probed if it's a
subnode of the geni-se-qup controller. Add a NOP driver for the
controller to correctly discover its child nodes.

Some devices like the UART and clock controller reference an RPM(h)
power domain. We don't support this device in U-Boot, so add
DM_FLAG_DEFAULT_PD_CTRL_OFF to tell DM core not to try and enable the
power domain.

devm_clk_get() returns an ERR_PTR on failure, not null. Fix the check to
avoid the board crashing when the clock isn't available.
Additionally, add the missing error handling for this function.

commit 1b15483deb ("misc: add Qualcomm GENI SE QUP device driver")
introduced support for platform-specific oversampling values, necessary
to configure the UART clocks on all platforms at runtime. However it
relies in probing a parent device. Despite the DM_FLAG_PRE_RELOC flag,
this is not done consistently during boot.
Instead, take another approach by relying on ofnode_ helpers to read the
serial engine base address and do the read directly. This fixes early
UART on boards with a non-default oversampling rate.

Now that we have time conversion defines from in time.h there is no need
for each driver to define their own version.

Starting from QUP v2.5 the value of oversampling is changed from 32
to 16, keeping the old value on newer platforms results on wrong set
UART IP clock divider, thus the asked baudrate does not correspond to
the actually set with all the consequencies for a user.
The change links the driver to a new Qualcomm GENI SE QUP driver
to get its hardware version and update the oversampling value.
Deliberately the code under CONFIG_DEBUG_UART_MSM_GENI is not touched,
since a wanted baudrate can be controlled by setting a modified
CONFIG_DEBUG_UART_CLOCK build time variable.

The name "se" is used in upstream Linux device trees and has been for
ages, long before this U-Boot-ism was introduced. Same goes for the
existing compatible. Get rid of that.

There is only one clock supplier to the serial IP, thus getting it by
name is not needed, also note that "clock-names" property is not listed
under doc/device-tree-bindings/serial/msm-geni-serial.txt, and finally
"se-clk" clock name is invalid, if added, it shall get "se" value like
it's already described in Linux device tree documentation.

CONFIG_VAL(DEBUG_UART_BASE) expands to CONFIG_DEBUG_UART_BASE or
CONFIG_SPL_DEBUG_UART_BASE or CONFIG_TPL_DEBUG_UART_BASE and allows boards
to set different values for SPL, TPL and U-Boot Proper.
For ns16550 driver this support is there since commit d293759d55
("serial: ns16550: Add support for SPL_DEBUG_UART_BASE").
