This series intends to comply with hexadecimal unit addresses for timer
subnodes as described in ("dt-bindings: Use hex unit address patterns").
Also update hexadecimal format for 'reg' property in these nodes. Take
care to update the boards accordingly. Note there aren't in-tree overlays
impacted.
Purpose is to avoid upcoming new dtbs_check logs like:
make CHECK_DTBS=y st/stm32mp135f-dk.dtb
...
stm32mp135f-dk.dtb: timer@4c00a000 (st,stm32-timers): 'timer@14' does not
match any of the regexes: '^pinctrl-[0-9]+$', '^timer@([0-9a-f]|1[0-3])$'
from schema $id: http://devicetree.org/schemas/mfd/st,stm32-timers.yaml
...

Use hexadecimal format for reg property. This has been raised since
("dt-bindings: Use hex unit address patterns"). The SoC dtsi file has
been updated to adopt hex for unit addresses and reg properties. So
update reg property in stm32mp15xx-dhcom-overlay too.
