dt-bindings: gpio-mmio: Correct opencores GPIO

In commit f48b5e8bc2e1 ("dt-bindings: gpio-mmio: Add compatible string
for opencores,gpio") we marked opencores,gpio to be allowed with
brcm,bcm6345-gpio. This was wrong, opencores,gpio is not compatible with
brcm,bcm6345-gpio. It has a different register map and is 8-bit vs
Broadcom which is 32-bit. Change opencores,gpio to be a separate
compatible string for MMIO GPIO.

Also, as this change rewrote the entire enum, I took this opportunity to
alphabetically sort the list.
