vboot: Remove get_sw_write_protect_state callback

Browse Source 
We've just decided to remove the only known use of the VBSD_SW_WP flag
in vboot (https://chromium-review.googlesource.com/c/575389), since it
was unused and never reliable on all platforms anyway. Therefore, we can
now also remove the coreboot infrastructure that supported it. It
doesn't really hurt anyone, but removing it saves a small bit of effort
for future platforms.
