Subject: [PATCH 2/3] mtd: spi-nor: Add support for spansion s25fs512s1

Add support for the spansion s25fs512s1 SPI NOR flash. This device has
a 64MB size (SZ_64M), dual/quad read capabilities and apply
s25fs_s_nor_fixups to handle specific chip behavior.

Erasing, reading and writing this flash device has been validated on
the Jetson AGX Orin platform using mtd_debug and dd utilities.
