soc/intel/common/fast_spi: Add Lockdown of extended BIOS region
This change adds support to Lock down the configuration of
extended BIOS region. This is done as part of
fast_spi_lockdown_cfg() so that it is consistent with the
other lockdown.
Change includes:
1. New helper function fast_spi_lock_ext_bios_cfg() added that
will basically set EXT_BIOS_LOCK.
