Sounds a bit weird, how about simplifying this to:

	spi_nor_set_4byte_addr_mode()

Or if you want to be specific:

	spi_nor_en_ex_4byte_addr_mode()

Unrelated to this patch itself, but can we just have one set_4byte
variant that uses WREN and drop the other one?
I expect sending WREN should be harmless even for cmds that don't expect
one.

Rest looks good to me.
