[PATCH v2 2/3] spi: allocate spi_board_info entries one by one

[Dmitry Torokhov]

Lists of spi_board_info entries registered with spi_register_board_info()
can be quite long; instead of forcing memory allocator find contagious
chunk of memory, let;s allocate them one-by-one, so they can be packed as
needed.
