The Counter subsystem git tree is now located on the kernel.org git
server so the MAINTAINERS file is adjusted accordingly. This set of
updates introduces the COUNTER namespace along with two new standard
Counter components: Signal polarity and Count capture. The big change in
this set is the introduction of Counter arrays which represent groupings
of components of the same type. Counter arrays are utilized by a new
Counter driver introduced here for the ECAP hardware on TI AM62x SoC.

Changes
* MAINTAINERS
  - Update Counter subsystem git tree repo link
  - add TI ECAP driver info
* counter
  - Move symbols into COUNTER namespace

  - Introduce the Count capture component
  - Consolidate Counter extension sysfs attribute creation
  - Introduce the COUNTER_COMP_ARRAY component type
* interrupt-cnt
  - Implement watch_validate callback
* 104-quad-8
  - Add Signal polarity component
* ti-ecap-capture
  - capture driver support for ECAP
* dt-bindings,counter
  - add ti,am62-ecap-capture.yaml
* Documentation,ABI,sysfs-bus-counter
