Hello build bot (Jenkins), Marshall Dawson,

mb/amd/mandolin: change EFS SPI mode from 1-4-4 to 1-1-4

With this change the flash addresses will only get transferred over one
data pin like in the non-quad SPI mode and only the data will get sent
over all four data pins. Since this gives the flash chip a bit more time
to fetch the data the host requested, this allows higher SPI frequencies
resulting in a higher throughput when bigger chunks of memory get read.
