Subject: [PATCH -next] thermal: fix mtk_thermal build dependency

From: Randy Dunlap <rdunlap@...radead.org>

Fix build errors when MTK_THERMAL=y and NVMEM=m by preventing that
Kconfig combination.

drivers/built-in.o: In function `mtk_thermal_probe':
mtk_thermal.c:(.text+0xffa8f): undefined reference to `nvmem_cell_get'
mtk_thermal.c:(.text+0xffabe): undefined reference to `nvmem_cell_read'
mtk_thermal.c:(.text+0xffac9): undefined reference to `nvmem_cell_put'
