nvmem: mtk-efuse: fix different address space warnings of sparse

Fix the following sparse warnings:

drivers/nvmem/mtk-efuse.c:24:30: warning: incorrect type in initializer (different address spaces)
drivers/nvmem/mtk-efuse.c:24:30:    expected void [noderef] <asn:2>*base
drivers/nvmem/mtk-efuse.c:24:30:    got void *context
drivers/nvmem/mtk-efuse.c:37:30: warning: incorrect type in initializer (different address spaces)
drivers/nvmem/mtk-efuse.c:37:30:    expected void [noderef] <asn:2>*base
drivers/nvmem/mtk-efuse.c:37:30:    got void *context
drivers/nvmem/mtk-efuse.c:69:23: warning: incorrect type in assignment (different address spaces)
drivers/nvmem/mtk-efuse.c:69:23:    expected void *priv
drivers/nvmem/mtk-efuse.c:69:23:    got void [noderef] <asn:2>*[assigned] base

The type of nvmem_config->priv is (void *), so sparse complains
about assignment of the base address with (void __iomem *) type.

Even if we cast it out, sparse still warns:
warning: cast removes address space of expression

Of course, we can shut up the sparse by marking __force, but a more
correct way is to put the base address into driver private data.
