Subject: [PATCH] nvmem: core: make nvmem_layout_bus_type const

Since commit d492cc2573a0 ("driver core: device.h: make struct bus_type
a const *"), the driver core can properly handle constant struct
bus_type, move the nvmem_layout_bus_type variable to be a constant
structure as well, placing it into read-only memory which can not be
modified at runtime.
