Tegra: use 'PLATFORM_MAX_CPUS_PER_CLUSTER' to calculate core position
This patch updates the plat_my_core_pos() and platform_get_core_pos() helper
functions to use the `PLATFORM_MAX_CPUS_PER_CLUSTER` macro to calculate the
core position.
core_pos = CoreId + (ClusterId * PLATFORM_MAX_CPUS_PER_CLUSTER)
