mfd: intel_quark_i2c_gpio: Revert "Constify static struct resources"

Browse Source 
The structures are used as place holders, so they are modified at run-time.
Obviously they may not be constants.

  BUG: unable to handle page fault for address: d0643220
  ...
  CPU: 0 PID: 110 Comm: modprobe Not tainted 5.11.0+ #1
  Hardware name: Intel Corp. QUARK/GalileoGen2, BIOS 0x01000200 01/01/2014
  EIP: intel_quark_mfd_probe+0x93/0x1c0 [intel_quark_i2c_gpio]

This partially reverts the commit c4a164f415.

While at it, add a comment to avoid similar changes in the future.
