Subject: [PATCH] nvmem: mtk-efuse: Enable GPU speed bin post-processing for MT8188

Like the MT8186, the MT8188 stores GPU speed binning data in its efuse.
The data needs post-processing into a format that the OPP framework can
use.

Add a compatible match for MT8188 efuse with post-processing enabled.

Cc: <stable@...r.kernel.org>
Fixes: ff1df1886f43 ("dt-bindings: nvmem: mediatek: efuse: Add support for MT8188")
Signed-off-by: Chen-Yu Tsai <wenst@...omium.org>

I'm not exactly sure about pointing to the dt bindings commit for the
fixes tag.
