flashchips.c: Adding support for ISSI IS25WP020/40/80

Browse Source 
This patch added support for IS25WP020, IS25WP040, and IS25WP080
SPI flash chips. The datasheet for these chips can be
found at: https://www.issi.com/WW/pdf/25WP016_080_040_020.pdf

Tested read, write, and erase functions on IS25WP080.
Test log:
Write: https://paste.flashrom.org/view.php?id=3698
Write test 2: https://paste.flashrom.org/view.php?id=3699
Erase: https://paste.flashrom.org/view.php?id=3700
