At boot, the devices under ETZPC control are secured, so should be
their GPIOs. As securable GPIOs are secured by default, keep the reset
values in BL2.

The "ngpios" property is deprecated and may be removed.
Use the "gpio-ranges" property where the last parameter of that
property is the number of available pins within that range.

No functional, change, but some improvements:
- Declare set_gpio() as static (only called locally)
- Handle the type ('open-drain') property independently from the
  mode one.
- Replace mmio_clrbits_32() +  mmio_setbits_32() with
  mmio_clrsetbits_32().
- Add a missing log
- Add missing U() in macro definitions

information, such as OTP NVMEM cell lists (phandle, name).
This list allows easy access to OTP offsets defined in BSEC node,
where more OTP definitions with offsets in bytes and length have
been added (replace hard-coded values).
Each board may redefine this list, especially for board_id info.
