Correct documentation for pxe_default_server, pxe_default_gatway,
and pxe_blksize. Only pxe_default_server is actually used (alias
for net_default_server) so capture this, and remove the other two.
Correct documentation for secure boot with UEFI to remove statement
that chainloader does not work with secure boot, as this was added
by a previous GRUB update. Correct the documentation for the
grub.cfg searching via network that will be done based on a given
MAC address (was missing the Ethernet Type - 01).

main branch.
Thanks,
