mtd: spi-nor: move spi_nor_write_ear() to winbond module
The "Extended Address Register" is winbond specific. If the flash is
larger than 16MiB and is used in 3 byte address mode, it is used to set
the remaining address bits. Move the write_ear() function, the opcode
macros and the spimem op template into the winbond module and rename
them accordingly.
