chromeec: Add wakeup delay after SPI /CS assertion

Some ECs may require a few microseconds to ramp up their clock after
    being awaken by /CS assertion. This adds a Kconfig variable that can
    be overridden at the mainboard-level which will force a delay between
    asserting /CS and beginning a transfer.

    BRANCH=none
    TEST=verified ~100us delay using logic analyzer
