chromeos: Remove CONFIG_VBNV_SIZE variable

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.
