The Intel SPI-NOR controller does not support the 4-byte address opcode
so ->set_4byte_addr_mode() ends up returning -ENOTSUPP and the SPI flash
chip probe fail like this:
[ 12.291082] spi-nor: probe of spi0.0 failed with error -524
Whereas previously before commit 08412e72afba ("mtd: spi-nor: core:
Return error code from set_4byte_addr_mode()") it worked just fine.
Fix this by ignoring -ENOTSUPP in spi_nor_init().
Fixes: 08412e72afba ("mtd: spi-nor: core: Return error code from set_4byte_addr_mode()")
