mxc: gpu_viv: On broadcast events try harder to get mutex.

Just trying once to get a mutex on global power events and then
erroring doesn't make much sense.  Especially when just looping
a second time always seems to succeed.  This may need to be
bumped up a bit, but I will leave it here until then.  I would
like to use this as a tracker to help identify what the lowest
possible value should be.
