mtd: spi-nor: sfdp: reduce stack usage in spi_nor_parse_sfdp()
Two large spi_nor_flash_parameter structures on a function stack
are really too much, and this can exceed an otherwise reasonable
frame limit:
drivers/mtd/spi-nor/sfdp.c: In function 'spi_nor_parse_sfdp':
drivers/mtd/spi-nor/sfdp.c:1717:1: error: the frame size of 1600 bytes is larger than 1536 bytes [-Werror=frame-larger-than=]
Allocate both rollback copies on the heap and use structure copies
for type safety.
