[PATCH v2 5/8] mtd: spi-nor: spansion: switch h28hx's ready() to use vreg_offset

[tkuw584924 at gmail.com]

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

s28hx is the sole user of cypress_nor_set_octal_dtr, which already
uses vreg_offset to set octal DTR. Switch the ready method to use
vreg_offset as well. This is a preparation patch. The goal is to use
the same s28hx methods for the multi die version of the flash.
