nvmem: mtk-efuse: Drop NVMEM device name

The MT8183 has not one but two efuse devices. The static name and ID
causes the second efuse device to fail to probe, due to duplicate sysfs
entries.

With the rework of the mtk-socinfo driver, lookup by name is no longer
necessary. The custom name can simply be dropped.
