x86: Stop building the vboot library using regparm=3.
This complicates things in a number of ways, including making GDB not work
properly because it assumes the standard ABI in some places. Measurements
show that it doesn't really make much difference performance wise.
BUG=None
TEST=Built and booted with coreboot and depthcharge on link.
CQ-DEPEND=CL:183490
BRANCH=None
