Tegra: memctrl_v2: platform handler for MC settings

This patch empowers the platforms to provide the settings (e.g. stream ID,
security setting, transaction overrides) required by the Memory Controller
driver. This allows the platforms to program the Memory Controller as per
their needs and makes the driver scalable.

Tegra186: read activity monitor's clock counter values

This patch adds a new SMC function ID to read the refclk and coreclk
clock counter values from the Activity Monitor. The non-secure world
requires this information to calculate the CPU's frequency.

Formula: "freq = (delta_coreclk / delta_refclk) * refclk_freq"

The following CPU registers have to be set by the non-secure driver
before issuing the SMC:

X1 = MPIDR of the target core
X2 = MIDR of the target core

Tegra186: clean CPU wake times from L2 cache

When entering C7, ATF disables caches and flushes the L1 cache. However,
wake_time[cpu] can still remain in the L2 cache, causing later reads to it
to fetch from DRAM. This will read stale values.

Fix this by aligning wake_time[cpu] to cache lines, and explicitly cleaning it
before disabling caches.
