fsp_broadwell_de: enable spi console
this enables spi console for wedge100s with broadwell_de. the console
size is 64kb. enabling spi console in `board.fmd` enables code which
calls into `timer_monotonic_get` (from `spi_flash_cmd_poll_bit`) and
`udelay` (from `ich_status_poll`). this patch selects `TSC_CONSTANT_RATE`
in fsp_broadwell_de's Kconfig to satisfy that.
