This is meant to test the sysfs entry for showing rc6 residency in
milliseconds. Remember, sysfs is a permanent interface.
v2: use new get_card interface to try "all" devices
check rc6p and rc6pp in addition to rc6
v3: rename rc6_residency.c to sysfs_rc6_residency.c
print better error messages
skip test if rc6 isn't enabled
v4: update to new sysfs names

Currently all we see is gem_read: ret == 0 failed, where it would help
to see the errno and/or the ret.

MI_MEM_VIRTUAL actually means use global gtt now, not setting the bit
means use ppgtt. On previous gens, not setting the bits ment 'use
physical memory'. So what, the usual confusion.
Note that for some odd reasong this is broken on gen6, but only on the
bsd ring. Unexpected.

Some test that trash the aperture necessarily need to take forever, so
add a little progress indicator to keep worried minds at peace.

Lots of tests need to create havoc to LRUs in the kernel or otherwise
need to shuffle things around a bit. So make a small array permutation
function available.

Some tests are higly timing dependent and others carelessly leave
active buffers behind. So add a helper to quiescent the gpu and call
it unconditionally when opening an fd in a vain attempt to make all
this race-condition hitting more scientifically sound.

Way too much copy-pasting going on here.
Also fix a compiler warnings in gem_stress while fixup things up.
