[tkuw584924 at gmail.com]

From: Takahiro Kuwano <Takahiro.Kuwano at infineon.com>

Infineon S28HS02GT is 2Gbit, multi-chip package, Octal SPI NOR flash. This
series reworks octal_dtr_enable part to support MCP and then adds ID and
fixups for S28HS02GT.

Tested on Zynq-7000 platform with Infineon SPI controller
