chromeos: Remove CONFIG_VBNV_SIZE variable

Browse Source 
The VBNV region size is determined by vboot and is not really
configurable.  Only the CMOS implementation defined this config
variable so switch it to use VBNV_BLOCK_SIZE defined by vboot
in vbnv_layout.h instead.

This requires updating the broadwell/skylake cmos reset functions
to use the right constant.
