CHROMIUM: MALI: Don't silently trash memory if there are > 2 regulators
When support as added to the mali code to support more than one
regulator the code was dynamic in checking to see how many supplies
were present but still stored supplies in a fixed sized array in
several places. Let's make it explicit that the hardcoded number used
to size the arrays is a maximum and also do bounds checking at init
time so we know we won't clobber memory.
See CL:1317240 for where the code was originally added.
