mtd: spi-nor: spansion: Add s25hl-t/s25hs-t IDs and fixups

Browse source

The S25HL-T/S25HS-T family is the Infineon SEMPER Flash with Quad SPI.

These Infineon chips support volatile version of configuration registers
and it is recommended to update volatile registers in the field application
due to a risk of the non-volatile registers corruption by power interrupt.
Add support for volatile QE bit.

For the single-die package parts (512Mb and 1Gb), only bottom 4KB and
uniform sector sizes are supported. This is due to missing or incorrect
entries in SMPT. Fixup for other sector sizes configurations will be
followed up as needed.

Tested on Xilinx Zynq-7000 FPGA board.
