dt-bindings: remoteproc: mediatek: Make l1tcm reg exclusive to mt819x
Commitca23ecfdbd
("remoteproc/mediatek: support L1TCM") added support for the l1tcm memory region on the MT8192 SCP, adding a new da_to_va callback that handles l1tcm while keeping the old one for back-compatibility with MT8183. However, since the mt8192 compatible was missing from the dt-binding, the accompanying dt-binding commit503c64cc42
("dt-bindings: remoteproc: mediatek: add L1TCM memory region") mistakenly added this reg as if it were for mt8183. And later it became common to all platforms as their compatibles were added. Fix the dt-binding so that the l1tcm reg can be present only on the supported platforms: mt8192 and mt8195. Fixes:503c64cc42
