intel-pinctrl for v5.10-1 

* Add last part of cleanup Cherryview driver to align with other drivers
 * Due to above clean up Cherryview and Baytrail drivers to use common API
 
 The following is an automated git shortlog grouped by driver:
 
 baytrail:
  -  Switch to use intel_pinctrl_get_soc_data()
 
 cherryview:
  -  Preserve CHV_PADCTRL1_INVRXTX_TXDATA flag on GPIOs
  -  Switch to use intel_pinctrl_get_soc_data()
  -  Utilize temporary variable to hold device pointer
  -  Switch to use struct intel_pinctrl
  -  Move custom community members to separate data struct
  -  Drop stale comment
 
 intel:
  -  Update header block to reflect direct dependencies
  -  Extract intel_pinctrl_get_soc_data() helper for wider use
