......................................................................

security/lockdown: Write-protect WP_RO

Add a wrapper function boot_device_security_lockdown which wraps
boot_device_wp_region to either lock (read/write) the WP_RO region
or the complete boot device depending on the Kconfig. One can either
lock the boot device in VERSTAGE if VBOOT is enabled, or in RAMSTAGE.

Tested on Lenovo T520:
The WP_RO region is write-protected.

Tested on Up Sqaured:
THe WP_RO region is write-protected in the verstage/ramstage.
