mtd: spi-nor: spansion: add MCP support in set_octal_dtr()
Infineon multi-chip package (MCP) devices require the Octal DTR
configuraion to be set on each die. We can access to configuration
registers in each die by using params->n_dice and params->vreg_offset[]
populated from SFDP. Add MCP support in set_octal_dtr().
