libpayload: mips: Add macros to convert to/from KSEG{0,1} addresses
Add helper macros to convert between physical addresses and KSEG{0,1}
addresses. Also get rid of the virt_to_{bus,phys}_offset variables
as these are fixed values.
As nobody seems to be using getpagesize() on MIPS, no need to keep
virtual.c.
BUG=chrome-os-partner:36258
BRANCH=none
TEST=Build and boot on Pistachio.
