dt-bindings: crypto: Drop obsolete mediatek,eip97-crypto

The mediatek,eip97-crypto binding is half abandoned. The driver was
dropped in 2020 as the Mediatek platforms use InsideSecure block and
the driver for it. All the platforms except MT7623 were updated. A
patch to update it was submitted, but never addressed the review
comments.

-Required properties:
-- compatible: Should be "mediatek,eip97-crypto"
-- reg: Address and length of the register set for the device
-- interrupts: Should contain the five crypto engines interrupts in numeric
-       order. These are global system and four descriptor rings.
-- clocks: the clock used by the core
-- clock-names: Must contain "cryp".
-- power-domains: Must contain a reference to the PM domain.
