ichspi: Add Jasper Lake support
Additionally, utilize CSSO (CPU Soft Strap Offset) to uniquely detect
the chipset when the CSSL (CPU Soft Strap Length) field default value
(0x03) on Jasper Lake is the same as Elkhart Lake.

Probing for Programmer Opaque flash chip, 0 kB: Chip identified: GD25Q127C/GD25Q128C
Hardware sequencing reports 1 attached SPI flash chip with a density of 16384 kB.
There is only one partition containing the whole address space (0x000000 - 0xffffff).
There are 4096 erase blocks with 4096 B each.
Added layout entry 00000000 - 00ffffff named complete flash
Found GigaDevice flash chip "GD25Q127C/GD25Q128C" (16384 kB, Programmer-specific) mapped at physical address 0x0000000000000000.
Found GigaDevice flash chip "GD25Q127C/GD25Q128C" (16384 kB, Programmer-specific).
This chip may contain one-time programmable memory. flashrom cannot read
and may never be able to write it, hence it may not be able to completely
clone the contents of this chip (see man page for details).
