nvmem_device is used at one place while registering nvmem
device and it is not required to be present in efuse struct
for just this purpose.

Drop nvmem_device and manage with nvmem device stack variable.

I'm generally fine with this approach

But this doesn't compile for me:
  CC      drivers/nvmem/meson-mx-efuse.o
../drivers/nvmem/meson-mx-efuse.c: In function 'meson_mx_efuse_probe':
../drivers/nvmem/meson-mx-efuse.c:252:9: error: 'nvmem' undeclared
(first use in this function)
 252 |         nvmem = devm_nvmem_register(&pdev->dev, &efuse->config);


Best regards,
Martin
