ARM: EXYNOS: Use platform device name as power domain name

The power domain nodes in DTS may be very generic (e.g. "power-domain"
for Exynos 5420) making it very hard to debug:

$ cat /sys/kernel/debug/pm_genpd/pm_genpd_summary
    domain                      status         slaves
power-domain                    on

Use platform device name instead so the names will be a little more
user friendly:
    domain                      status         slaves
100440e0.power-domain           on
