armv7: preserve bootblock invocation parameter
Some platforms may pass as a parameter the maskrom or vendor startup
code information when calling the bootblock.
Make sure the bootblock startup code saves this parameter for use by
coreboot. As we don't want to touch memory before caches are
initialized, save the passed in parameter in r10 for the duration of
cache initialization.
Added warning comments to help enforcing that cache initialization
code does not touch r10.
BRANCH=storm
BUG=chrome-os-partner:30623
TEST=with the rest of the patches applied see the QCA uber-sbl report
in the coreboot console output.
