ARM: cache-l2x0: fix L2 maintenance for R3P1_50
Do flush and clear by set/way instead of by-way by enabling
errata 727915 for pl310 revision R3P1_50.
By-way maintenance doesn't work with enabled lp2_in_idle on
Tegra3 platform using R3P1_50 revision of pl310.
Debug register access causes hang when
CONFIG_TRUSTED_FOUNDATIONS is defined. Don't access those
regeisters if CONFIG_TRUSTED_FOUNDATIONS is defined.
