intel-gpio for v5.1-1

Small clean up for Intel PMIC GPIO drivers, includes:
 - optimizing IRQ handlers by usage of for_each_set_bit()
 - sorting headers alphabetically for better maintenance
 - conversion to SPDX identifier

The following is an automated git shortlog grouped by driver:

crystalcove:
 -  Convert to use SPDX identifier
 -  Sort headers alphabetically
 -  Use for_each_set_bit() in IRQ handler

msic:
 -  Convert to use SPDX identifier
 -  Sort headers alphabetically
 -  Remove duplicate check in IRQ handler

wcove:
 -  Convert to use SPDX identifier
 -  Fix indentation
 -  Sort headers alphabetically
 -  Allow return negative error code from to_reg()
