mtd: spi-nor: Add support for Infineon s25fs256t
Infineon S25FS256T is 256Mbit Quad SPI NOR flash. The key features and
differences comparing to other Spansion/Cypress flash familes are:
- 4-byte address mode by factory default
- Quad mode is enabled by factory default
- Supports mixture of 128KB and 64KB sectors by OTP configuration
(this patch supports uniform 128KB only)
