tests: rc6 residency test

Browse Source 
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
