dt-bindings: mfd: syscon: Document the GPR syscon for the NXP S32 SoCs

The NXP S32 SoCs have a GPR region which is used by a variety of
drivers.  Some examples of the registers in this region are:

  * DDR_PMU_IRQ
  * GMAC0_PHY_INTF_SEL
  * GMAC1_PHY_INTF_SEL
  * PFE_EMACS_INTF_SEL
  * PFE_COH_EN
  * PFE_PWR_CTRL
  * PFE_EMACS_GENCTRL1
  * PFE_GENCTRL3

Use the syscon interface to access these registers.
